So i have a 2021 v7 and am wanting to put straight pipes on it. I know this requires a ECU re-flash and that requires a map as well as a program and chord to hook to the bike. I am looking for the links to these items. Link for the program to run the map would be nice. Link for the chord i will need and maybe just some information on the process. Pros , cons etc. The sound of the guzzi with the straight pipes or just shorty pipes with minimal muffler is what i am looking for. I do know there are down sides to this but the fact that the only aftermarket pipes that you can get for this bike are in the $1000 range it would be nice to maybe learn to a new skill and figure out what im doing in regards of mapping a bike. Seems like i am now willing to trade my time to save some money to get desired effect.

Put in “New improved Guzzidiag Tutorial” into the search bar at the top/right of the WG homepage.
It’ll explain what you need.

How do i know what ecu is in my bike?>

How do i know what ecu is in my bike?>
If you download a manual, that will tell you, but in any case when you open Guzzidiag, there is a dropdown menu box listing all the models that can be accessed.
I am sure that your V7 is there.
The ECU will appear in the bottom left corner once you’ve gotten hooked up.

Try a search, you will find all that has been discussed over & over, look in workshop manual for ecu model.

Stupid idea.
You bought the wrong bike.
And it's even a stupid idea on Harleys too.
-
Here's my opinion, feel free to disregard it.
Guzzis with unmuffled pipes have a horrific sound, matched only by a similarly-equipped Korean lightweight streetbike. I raced with Mike Tiberio, and even his finely-tuned, 2 into 1 megaphone equipped racer had a horrid tone.
To be sure, I am not a fan of straight pipes even on something as traditional as a Harley Panhead or Iron Sportster so I get that my taste is perhaps not mainstream. So at the very least, I'd find some inexpensive generic straight-through mufflers to try out. My '89 Mille GT has a set of long body Mistrals on it (very expensive tho) and it's about the nicest sounding bike I've ever heard. It's strange that the difference mufflers make on these bikes is so much broader than say, H-D. To me anyway. Ramble over.

It’s a touchy subject at best guys as we all realize that “straight pipes” are illegal in every state as well as annoying to the majority of the public.
Now that the particulars are out in the open, let’s remember to offer our responses with respect.

hey thanks john. and to yall im pretty sure i bought the bike i wanted and its not very cool to be here telling me that something is stupid im doing with my bike im sure something that you do with your bike people think is stupid as well but who am i to tell you what to do with your things. Mistrals are very much still a option i just need to pony up the money to buy them. I would still like to learn about this ecu and maps. I am not one to bring any bike i have to a shop. Again I did not create this thread to be an argument of what people thought was a good idea in their opinion i just wanted some direction in learning more about the ecu and what was possible with this motor and the fuel injection. I have read some of the other threads and they all seem to become just a argument of the same nature i was hoping to avoid that. Thanks to all of you guys for your feed back and your opinions as well as some of the facts. the thing i love about motorcycles is that they are all unique to the rider. It is something cool any way ill get off my soap box.

I changed the exhaust on my V85 because I damn well wanted to and therefore it makes it ok.
Stay on your soap box, because you’re absolutely right.
Dan will handle it…

Respectfully - I would argue you did ask for opinions, and options, and that we are giving you real world responses that mimic what you should expect from others.
Heck, "who are we to tell you" - anything? That's the way the world works, but you also asked so an attorney might say that you opened the door.
But I'll give another reason why someone else gets an opinion. It's because your actions will affect not only everyone you physically come within proximity of, but by also by extension, that will potentially affect everyone who comes into contact with the ones you piss off.
No man is an island, and your actions may very well reflect upon me or anyone else here someday.
Ok, so with that out of the way, the technical reason it's not a smart idea is because no matter what you do straight pipes will castrate performance almost everywhere that matters in the rpm range at a cost of noise and inefficiency.
Yes Mistrals may be much more expensive but the cost to you, performance, and society is much less.
And just to be clear, I put my money where my mouth is and have had nothing but stock exhausts on every motorcycle I own currently and have ever owned, except two (a used Buell that came that way and is gone now, and my first ever Harley back in the 90's, but even then I used street legal mufflers).
Anyway I'm happy to discourse about the technical ins and outs to help, but my reader's digest version earlier still applies for reasons I've now clarified.
So I say if you must run louder than stock (louder than legal), it would be a good idea for a lot of reasons to at least use a muffler that matches well and promotes proper exhaust gas scavenging.

Maybe you would consider something like this.

Your engine is fundamentally the same,
Baffle in https://youtu.be/Li8qvFVuAJ8
Ignore the slight surging when stone cold, within 30 seconds it settles and idles perfectly.
It’s all very doable.

I installed these MIVV shorties on my V7 III if you choose to go with some slip-on mufflers. Much lighter than stock and has a great sound. Pretty reasonably priced too.
Edit: I should say WERE reasonably priced. I paid $325 for a set 3 years ago and they're now $500. Guess that's inflation for you...

I had a Convert with straight pipes and fish tails. I was the only one still standing at a generic motorcycle rally so I was sent to get the beer. The campground was out in the country and I left with the pipes talking.
when I returned with the two cases of beer on the luggage rack a Harley rider said I thought you was going to tear that old thing apart as I never heard you shift. I never said a word.

I ran straight fishtails on my old T-3. It performed much better with a set of Lafronci Competizione mufflers. ( it also sounded better) A straight pipe on a smallblock guzzi is going to sound shrill. Think of it like a musical instrument.... flute vs tuba. I'm a fan of Bub Conti replicas. They are a straight through design, with a perforated core that tunes out the higher frequencies. (like a glasspack ). Check out Cone engineering. https://coneeng.com/index.html (https://coneeng.com/index.html) They sell high quality mufflers at great prices. I run one of their reverse megaphones on my LeMans SE.

+1 on Cone Engineering mufflers. Just be careful choosing as they sell them in two versions - LOUD and REALLY
LOUD. Better yet, stuff a set of Contis on there. As loud as they are, they are still Contis and thus above the law. It’s your bike faux_Guzzi. Do whatever makes it yours. Everything is reversible.

Absolutely. As the saying goes "If you can't live with the answer, don't ask the question!"

My fishtail straits, jetted right, Got away from one 8V Stelvio & caught the tail of another one. Everyone looks at the barking dog. I had no mufflers so I put these on. Real loud but hauls butt. Might change out for Dunstall replica's this year if I make up a X over, been on there for 17yrs.

IF, you put straight pipes on a bike, especially a big V-Twin, they should be at least 8 feet long in order to look right and sound right!
I thought everybody knew that........
And none of this sissy, skinny, chrome crap pipe either!! At least 2" diameter black iron water pipe!
Do it right, or leave the fabrication to the professionals!!!!

It's OK, you're amongst friends here... pour yourself a drink, sit down, calm down, and tell us how you really feel.
-
Geez, note to self, never talk about straight pipes at a guzzi rally unless I have a muffler in hand to fight back with.
-
You could test the sound pretty easily. Just take off the mufflers and see if you like it.

Times have changed, in the old days copper plumbing pipes were the proffered material for the grizzled suspender snapping Guzzi owner.

I settled on the leo vince slip on lv-10. After talking with my parts guy at my local shop he suggested them as an alternative to the mistral and agostani. They were at least 300 cheaper then then the others and will clean up the back of the bike a bit. And john you are absolutely right and i value everyones opinion on this forum and am glad this is a space to bounce ideas off. They have used these slip ons on several guzzis at the shop and have not had any complaints. for sure my other choice would of been mivv but I will let you know how it goes thank you for the advice. i knew going into this conversation it was going to be a brute but thanks again guys all of you. now to get out the laptop and start learning about this mapping.

I had a Vince on my 2008 Tiger 1050. Great sound and build quality.
-

I stand corrected! Large diameter copper pipes is also acceptable. The exhaust temper will discolor the copper pipe to a beautiful rainbow of multiples hues!
Style and sound are both very important! Prioritize one over the other as you see fit, cause, after all, it is YOUR bike!
-
If one is on a tight budget, PVC could also be used to extend the length of one's straight pipes. But not within 6 feet of the cylinder. Only metal should be used in the first six feet of the exhaust system.
-
Remember to buy the ABS PVC. The white crap gets dirty and looks cheap.

Tex will you tell us about the time you took off the mufflers and rode around in the Harley camp at zero dark thirty in the morning when they were trying to sleep ? Hilarious!
Tex may not even remember it for it was one among similar things that he did . Tex went to many rallies that most riders only think about. Anyway, he was thinking some Harley riders, you know the type, were making a spectacle of themselves with unmuffled engines and generally being rude late into the night. Tex is not one to complain but he gets up very early so he took the mufflers off his Guzzi and proceeded to rattle the empty beer cans laying around the camp as he rode around while they slept ,or tried to sleep wondering what the he*l kind of bike was that . I can’t do the story justice, maybe the master himself will!
-
I wouldnt straight pipe off the headers, but that is an aesthetic choice for me. I have had and would run again- fully open/hollow 'mufflers', megaphones, or reverse cone pipes without hesitation.
-
this goes without saying, but I'll say it anyway.
The color scheme for copper straight pipes is the same as for copper sealing washers. The copper color has to fit in with the paint scheme and the rest of the bike or it just won't look right!
-
I have a Leo Vince set on my V7III and have been very pleased. Louder than stock but not annoying. They really do clean up the looks nicely and with my basic GTM re-map there are no downsides at all.
They were considerably less expensive than Mistral or Ago which was a bonus.

I use nickel based antisneeze compound instead of copper based antisneeze for that very reason.

Less power and more attention. Personally, I ride way too fast to risk the additional law enforcement attention. AND I like power. Normally I'd say 'you do you' but this sort of modification forces YOUR choices onto others. That is not acceptable. If others do not appreciate you forcing YOUR choices on them, and express it as such, you can accept their displesure as you expect them to accept your noise.
-

Yeah, sometimes it is a pain, but having an eye for the smaller details, and going the extra mile, always pays off when the job is done! :thumb:
Of course, the nickel based stuff is also an excellent sun blocker......

John A,
I rode the unmuffled Guzzi at 5 AM thru the rowdies camp and watched them crawl out of their furniture pads (furniture are free) pads to see what the racket was. One said, "it's a *^&% Moto Guzzi. Another time I pulled a muffler off and was putting it in my tent when a biker said what you doing. I told him I take off the muffler so I can hear if anyone is stealing my bike during the night. Somehow I survived all the wild biker campouts.
Don't even mention long distance rides and the mileage on your Guzzi at these events.
At home all my bikes were quiet as I left for work at odd hours. I was getting a title xferred at the tag office when my neighbor that worked there said getting another Guzzi, huh? Her co-worker went ballistic about how she'd hate to live in a neighborhood with a biker. My neighbor jumped on her and said I never hear him except laughter when he is giving kids rides in his sidecars.

faux
I put a pair of the eBay 12" shorties in my V-7II for a year or so . I used the long DB-Killers to keep the noise level down (a little) out of respect for my neighbors .
There wasn't no need to re-map , it ran the same way as the factory pipes.
After a while I got to missing the mellow tone of the factory pipes and put them back on. As the Original mufflers aged they naturally got louder ... that where I'm at now at 30,000 miles.
With the "Shorties" on I would be really "EASY" on the throttle around town so I never had the Legal Problems that can come with being irritating in public. Life can be full enough of head-ache's as it is , without going out of my way to find more .
Good luck with your project . :smiley:

Deb and I were on our way to the Italy TX rally. It was an easy two hundred miles from home near Shreveport and we liked to travel on backroads. She was on an Ambassador and I was on a Cal2. We stopped for a break and as we walked around a bit both of us happened to look at the back of her bike and said oh dear at the same time. I was looking at the mufflers where one baffle was hanging halfway out and the other one was gone. She was looking at the expired plates.

I don't know about the newer engines, but for Loop frame and carved Toni framed bikes, I always likes the way Dunstall megaphones looked and sounded. Even the crappy Emgo ones that only lasted a few years sounded pretty good.
That sound probably cost a couple horsepower, but oh the sound.
