2013 Stelvio

[Bonafide Bob]

I am a new owner of a 2013 Stelvio. I would like to get an exhaust without the cat converter and get it to breath a little better, from what I understand when I change the exhaust and breathing I will also need to download a different program. Any help and suggestions will be appreciated.
  Thanks Bob

If I were you, I'd ride it the way it is!!!! At least for a while. I think you'll find it performs very well the way it is as long as it's properly tuned. Once you start down that road it's a slippery slope, and quite expensive. I went that route with my '09 and the cost FAR outweighed the gain, IMHO. I've left my '14 alone and am very happy.

 :+1  My thoughts exactly!!  My '12 has 26K miles on it and it's bone stock.  Right out of the box, properly tuned and maintained the NTX will perform very well for you.

I'd love to see some dyno results from changing the can on the Stelvio.  My gut feel is that the gain is insignificant, if any at all.  The only benefit is less weight.  If you save 20# that's still not significant on a bike that weighs 650# or more.  The stock setup works just fine for me.  As I recall, Pete Roper has found that the common intake/exhaust mods actually yield less horsepower and torque.

Any mods that reduce emissions?

The Stelvio NTX is already emissions compliant in Europe/UK and all 50 States of our country.  What additional reductions do you think are necessary?

What makes you think that the factory muffler restricts flow?

Nothing necessary, but if less is better than I was wondering if anyone has played with mapping or other programming tricks with emissions in mind.

 I don't see how it could flow good thru the cat converter and the heat coming off the stock exhaust it nearly unbearable.

A few owners on the Adv Rider website have made adjustments to the ECU mapping on their bikes to improve the fueling during certain load/speed conditions.  The changes, for the most part, are to increase the fueling and reduce a lean operating condition that is probably required to meet the emissions regulations.  These changes tend to increase, rather than decrease, engine emissions.

My 13 Stelvio is the first bike Ive ever owned that I haven't felt the need to screw with as far as exhaust and tuning is concerned. My previous bike was a 12 Griso and all the exhaust and tuning did was to make it loud and sound faster but in reality just louder and wasted money I could have used for tires and such. I assume your Stevio is new and if that's the case when you hit 8-10K miles it will finally be broke in and run even better than it does now. My friend who rides a very loud Harley always comment about how beefy my bike sounds and was surprised to learn my exhaust is stock.

[Vasco DG]

You can stick on another pipe and it won't flow significantly better than the factory one, in fact it will probably be worse. Yes, the way the bike behaves can be improved a lot by re-mapping but this is not simply a matter of adding more fuel, there are a host of adjustments to fuel, both in the main and delta maps and possibly timing before you can start looking at the correction tables for temperature, altitude and the like.

The 2O2 Stelvios are actually better than most in terms of their factory mapping but there is still room for significant improvement. It's not just a matter of using the bike as a dart board and chucking stuff at it though. Best idea for ideal results would be to log map each cylinder individually. You can do them one at a time.

I put the first 75 miles on my new '13 Stelvio and everything was good but it did have a lot of decel popping.  Can this be "touched up" at the 600mi check by the dealer?

[Vasco DG]

Check the bypass screws. Betcha they are both open.

I'm running a MIVV slip-on muffler on my NTX along with a custom fuel map. It runs like a bat outa hell in mating season.

I didn't install the aftermarket muffler in search of added horsepower but because I prefer the sound of it to the stock muffler. The MIVV is also significantly lighter in weight but, again, that was not my prime consideration.

I don't want an obnoxiously loud exhaust but I do like the deep rumble provided by the MIVV.  I'm even running it without the baffle lately.

I've switched back and forth to the stock muffler and the MIVV certainly does not seem to diminish the power delivery. My seat of the pants feeling is preferable with the MIVV over the stock muffler.

Do what you want. It's all subjective, about preferences and not dyno numbers. Otherwise we'd all be riding hyper-powered 4-cylinder sewing machine bikes with no personality.

I would recommend learning about Guzzidiag and Beetle maps.  No problem changing out to an aftermarket exhaust  (I have and would recommend Mistral), but leave the DB killer in, and leave the intake alone.  Once you try that (and enjoy it immensely) for a while, you might find that you don't need anything else.  However, if you do want to do more, you will be starting from a happy place.  Trust, me, you can throw a ton of money at these things and not get anywhere.  For almost free (donation to the folks making these tools available ), you can transform your bike.

Was the dealer Cleveland Moto? How do you like the Stelvio as compared to your GS?

[Spuddy]

With the stock can I think the '13 Stelvio exhaust note is sweet.

I was at a dealer last weekend to look at some of the V7's they had in stock.  There was a 2014 Stelvio there so I thought I'd check it out.  While sitting on it a salesman walked up and said "So what do you think?  Do you like it?" and I replied "well yeah, but maybe a little more if I could put my feet on the ground".  It was in a wheel chock so I'm thinking that had it lifted at least an inch higher than normal.  I have a 30" inseam and I could barely put the front tips of my shoes on the ground.  He said "not a problem, the Stelvio is one of the easiest bikes to lower.  We have a 2013 in the back that's a super deal right now".  I said thanks and continued to look at the other bikes.  But after reading some of the posts here I started to wonder - how low can the Stelvio go?  Can it really be lowered to a point where someone like me can flat foot it?  Just wondering.

Yes it can.  To my knowledge, you'll need to change to the Griso shock, move the forks up in the triple clamps, shorten the side stand and remove the center stand.

I suggest you PM "Fortrider" on this website.  He and his wife were the owners of the Fort Collins dealership before selling and retiring.  He lowered a Stelvio for her to ride and can give you the details.

Hey thanks Chuck.  Information much appreciated.  That opens more choices if it can be done.  Any kind of impact on performance/steering, etc?  Sorry, I'm not very knowledgeable in this area.  I would not be worried about clearance as I wouldn't ride on anything beyond pavement other than a gravel road and that would not be often.  More the role of a touring bike.   I currently have a '04 RoadKing and I'm starting to look at bikes with abs.  In all truth, I was at the dealer to look at the new V7's and ask about the V7II's.  But having adv touring bikes (BMW F650 & 650 VStrom) in the past I've always had an appreciation for this style of bike.

[ChuckH]

.....  Any kind of impact on performance/steering, etc?....

My understanding is that lowering the bike will reduce the suspension travel and have some effect on the handling.  I'm certain that "Fortrider" can give you a more complete and accurate accessment of the changes.  Ride safe.
