70tre Scrambler Exhaust for V7 - Pics and Video

[Dirk_S]

Just installed 70tre’s high mount scrambler exhaust from Unit Garage onto my V7II Stone, and first impression is greater than expected.

There isn’t much info on these pipes out there, so I took a quick-and-dirty walkaround video on their inaugural ride (Mods, any chance I can get this to embed?):

https://youtu.be/wSDvUx8OanI

Pics:

• Weight: These and the stock twin pipes were placed on the scale. Stock exhaust = ~27 lb.; 70tre exhaust = ~13 lb.
• dB killers appear to be removable; allen bolt located on the underside at each end.
  
• Instructions were 90% legible, Italian-to-English translation was better than most cheap Chinese-to-English instructions. A couple areas were confusing, but it was easy enough to figure it out along the way.
• A third of my time was spent honing my dexterity rerouting the lambda sensors. Left side had to come up overtop and behind the oil breather; right side needed a little bit of work, too.
  
• Unit Garage confirmed that no re-map is necessary. I’m thinking about doing it anyway, because I’ve never gotten it done.
• The black grills on the mid-section were extra. They protect the heat shields. I feel them against my leg, possibly more than I’m comfortable with. Will stick with them for a trial period to decide whether or not to keep them.
  
• I bought these conceding to the fear that I may lose easy access to the side cover/battery, but they stick out plenty enough for the Allen wrench.
• Another fear—I do a few multi-day trips every year, and like to have pannier mounts on both sides for balance. It appears that my right-side Givi rack may still work without any necessary modification; could just require an extra inch of spacers, not much more than what’s on the opposite side, really.
• These pipes sound very raw and tractor-like, a plus to my ear.
• I’m not seeking loudness, but I do believe they’re little louder than factory.
• Stainless steel, they went gold pretty quickly (as in immediately)—does that indicate steel quality, or does it just point out how lean the bike runs?
• Paired with the new rear fender, wheel removal should go more quickly.
• Looking forward to replacing the cast wheels with spoked wheels converted for tubeless tires in the not-too-distant future.

Hoping they’ll hold up. Now I have a stock system to sell to help buy back the kidney I had removed in order to pay for the new pipes.

Those look sweet! I remember wanting these exhaust back in the day but was too nervous to pull the trigger for something that needed to get shipped from Italy and had no reviews online.

How are the weight savings? Are the DB killers removable?

I highly recommend you get a remap and just plug the O2 sensor holes. All stainless pipes will turn gold after awhile, looks better than chrome in my opinion.

[greer]

Wow, what a piece of work!  I hope you decide to lose the black grills.

OP edited for quick reference. Looks favorable :)

Sat on it again this morning, which was enough to end the trial period more abruptly than planned. These fellas get the boot.

Look great. Interesting, true dual and no cross over? I like how they are tucked in as opposed to the Arrow that sticks way out. I swapped the Arrow can for the Mistral from MG Cycle which is better, but these look great. Congrats!

[Dirk_S]

No crossovers/h-pipes.

Agreed on the Arrows being set too far out. I honestly didn’t even think about the option of getting the Arrow exhaust and replacing the silencer because of that. Also too far back for my taste. The Agostinis set back even farther. AF1 has a marked-down Arrow, and I’ve seen one or two display-shelf Arrows marked down, and I bet there could be a savings of a hundred or two over this one if shipping smartly.

Sorry, I hate this type of one sided exhaust system
- no possibility of a pannier on the RHS
- possibly dangerous to the passenger
- ugly naked LHS of bike
I know others will love them.....
Why did they not make it 2-1 - more compact and save weight and cost?
AndyB
BTW are the lambda sensors deleted with this system?

As stated in the OP, these pipes are half the weight of the stock pipes. I think 13 lb is pretty helpful. Also noted that I will be able to use the RHS pannier rack, and that the lambda sensors were rerouted; you can see their placement here (one is behind the pipe):





To each their own. For me, it’s form AND function. Win/win.

[Andy1]

Hi Dirk,
We all make our bikes how we want them - I am sure it is fine for you - just not for me.
Sorry,  I missed the lambdas were still fitted but I do wonder if a RH pannier will fit (you were not sure in your OP and mentioned needing spacers).  Fit too close and plastic panniers will melt.  Good that weight is saved but a 2-1 would save more weight and might allow the silencer to be pulled in tighter?
Having the silencers lower just seems inherently better (lower c of g, away from legs and panniers) and the Mistral silencers I use on my V7 do the job for me and also save weight.  Before buying my V7 I looked at other bikes and discounted those with high level exhausts as I use panniers on a daily basis.
No intention to offend, just a different perspective.

I like the look of the exhaust, but not the look of the bottom frame of the bike without pipes there.  I do wonder what one pipe per side scrambler pips would look like though. 

If I ever change the exhaust on my V7III, and that is a big iff since I have never done that on any of the bikes I have ever owned, I would go for the short exhaust that ends at the rear axle instead of past the rear tire.

I think I'd leave the grills on, but paint them silver.

Ehem..........  If I had this system, the extensions would only need to be 2-2.5" as opposed to 3.75" Work very well so far, about 5K miles on them. THe screen is a repurposed Norge Large Screen. It has since been dropped about 3" and I cut a relief for the headlight.

Whats the little electronic gizmo by the brake arm in the 3rd pic?

[Andy1]

Wow. Those panniers are so far back......look at the panniers on ratguzzis’s bike.....panniers used to be as far forwards as possible to put the weight between the wheels.  And as close to the centreline of the bike as possible to keep it narrow and keep the weight central.  It seems fashion is now more important than function, which is slightly counter-guzzi

Flux capacitor ;-)  I recently stripped all the accessories/bags.racks off the Stornello and moved the TPMS down there to declutter the bar area. Will be moving it back soon.

On the bag mounts, I agree, would prefer them to be about 2-3" forward, but that is the Hepco Becker mount. Likely is to facilitate the rear cross brace. In normal V7 situations, they could also be about 1.5" in closer to the center line of the bike. Only so much you can do with a universalish mount.

I’m still bouncing back and forth whether I want them on or not. Not the most comfortable, but they would ensure more security against abrasion and possibly drops.

[Mayor_of_BBQ]

leave the guards on, looks better and keeps your leg off the hot pipe

[greer]

Better keep them, Dirk.  They must've grown on me, because it seems the pipes look wrong without them.  I do like Rich's paint idea, though.

Like these much more than the Arrow high pipes. Will need to see if they're available for the Mk 3. (Update: where did you buy these? I can't find a seller online.)

I have shorty mufflers on my bike but think I still like the look of high ones.

[Dirk_S]

These are only available for the V7 I and II unfortunately. I did a cursory search for high pipes for a V7III should the occasion occur that I happen to win a V7III in a raffle *cough*, and there doesn’t seem to be any production options besides the Arrow and Agostini. Both are 2-1. The Agostini silencer sticks pretty far back.

The Arrow kit is over $2K and the Ago looks like a friggin' bazooka. I like the Arrow 2:1 Rebel set but will likely go with MIVV Ghibli shortly mufflers at 1/2 the price

Hi Bulldog,
I also have the HB mounts on mine but use the HB alloy boxes and the rear of the boxes do not extend as far back as the rear of the bike.  I would also like them further forwards but the V7 is quite a short bike and if they were more forward then they would interfere with the passenger pegs.  Looks like the alloy boxes mount more forward than the plastic ones though.

Things like exhausts and accessories can become a philosophical debate: should fashion override function?   Personally I rate function over fashion and try to make changes that improve the operation of the bike.

I honestly don’t see too much difference between either boxes. I wonder if it could be the angle of the pic?

I’m like-minded. I’m not often going to throw a thousand dollars toward something that just looks cooler. If that were the case, I’d have bought the blue special at the dealership over this gray Stone.

I wanted less weight, better capability/protection off-road (think adventure bikes with the high exhaust], jettison the chrome for better durability (bike is stored outside 365 days/year in New England), makes changing a rear tire easier, and the ability to still rock a right side pannier. This ticked all those boxes for me thankfully, and all those boxes are in the Function category. That it looks nice (to me) is double the pleasure, double the fun.

Well, I dont think my Stornello will win any 'cool fashion' contests.... lol  I made the modifications to suit my needs. Some hate it, claiming I have marred Italian styling perfection (grow up) and I could care less. They work for me, as an all/any road long distance bike, the Stornello is comfortable, fast 'enough', reliable, gets great fuel mileage, tons of character, and the bags carry all my gear for my commute (leave all riding gear with the bike) and 2 weeks of clothes, camping gear, tools and 'stuff'. I have even gone grocery shopping and fit more in the 3 saddle bags than my wife can in her trunk ;-) 

If you are using the same HB racks, the bags end at the same place, as the locks are right at the back of the rack.  They are ugly as sin, but tough, and waterproof, and easy on and off. I do wish they were 2-4 " farther forward, but would make a passenger impossible, so fair compromise.

For day trips and running around town, I just use a small tailbag it shares with the Griso.

[Andy1]

Hi Bulldog
Yes, the angle of the photo made your bags look more rearward than they are.....apologies.
If I had a V85TT the position of the rear top rack would worry me - that really does hang off the back of the bike.

Going back to the main thread here.....when I fitted my Mistral pipes I really wanted the shorter ones but had to go with the longer ones to retain the centre stand stop bracket which came off the LHS exhaust mount bracket.   How does it work with a high level exhaust?

The other little thing to think about is to make sure that the passenger does not burn their stockings on the hot pipe -  which can also result in a nasty burn in a delicate place.....

On the V7II, there wasn’t anything connecting the exhaust to the center stand (not the H&B one, anyway—the stop and stop plate are underneath at the crossmember).

The other little thing to think about is to make sure that the passenger does not burn their stockings on the hot pipe -  which can also result in a nasty burn in a delicate place.....

The mid-section has a heat shield overtop the pipe, which my leg also lies against. It’s certainly warm, but hasn’t caused me alarm any different than resting my leg against the stock heat shield at stops. Having the optional grills on provides more distance from the shield if desired, and the optional passenger footpeg protection bracket shown below keeps pant cuffs, etc., from entertaining the idea of straying toward the wheel or catchable parts. The plates are universal and I think a nice safety option. They might be unnecessary once I reinstall the RHS pannier rack.

No worries....

I have the Hepco Becker Center Stand for the Stornello/scrambler, which places the 'stop' in the center pivot section of the stand, so no issues, though it does hit the rear caliper unless you adjust the stop. Makes it look as though the stand is hanging down. Took a bit to get used to the look, but it is what it is. Because of the 420mm rear shocks and a 3/4" taller fork spring static height, the center stand doesn't get the rear tire off the ground    It is 'stable' enough, but less than ideal. If I put a 2x6 on the ground underneath, it is perfect. Eventually, I will pull it off and have someone weld small 'feet' on to the center stand legs, but it is good enough. When I NEED the rear tire off the ground to service, etc, I just put the block of wood under the feet. Otherwise, I like using a center stand 90% of the time, especially when loading bags. The taller stance also gives a crazy steem lean angle on the side stands, but the extra clearance and ride height (about 3/4" unladen, 1/2" laden/seated) is a good thing.

I havent taken a passenger on the Stornello yet, but the stock shields do a decent job. The requisite over the ankle boot and thick riding pants will make it a non issue. I really like how the system posted by the OP is tucked into the bike, looks as if it doesn't stick out beyond the rear turn signals. My Mistral STARTS at the outer plane of the turn signal and sticks out another 3". I wonder if the stock HB racks might bolt straight up, or may just need a small spacer to clear them. I wouldn't make the change myself unless I needed to replace the system.

In all, I am very happy with the modifications and their function. The bag setup, larger screen, Stelvio hand guards, and heated grips makes this a great year round, all road bike. I'm never going to chase KLR's on the TAT or rocky trails/mud, but for off road, grave, dirt roads and trails, the bike is sublime (with TCS off). The extra weight and suspension upgrades have also settled the bike and it is a surprisingly pleasant mile muncher.  Beetle Map and mistral makes it a blast to ride. Has become my favorite bike of all time..... 6 years ago, I was on an FJR and had 100HP+ Liter+ bikes. NEVER in a million years did I think I would be happy on a 40HP bike.

[Andy1]

Totally agree - happiness on a bike is not HP related!

Interesting that HB use a different centrestand stop to MG.  A bit of a detail but if I had bought an HB centrestand I could have fitted the short Mistrals....too late now.

I like your screen and hand guards and heaters.  I have similar on my R100R BMW with leg shields as well as that is my longer distance / winter bike.  My V7 I keep for summer.
