    As posted on the registry page, I just got my brand new V7 Anniversario, and of course am immediately thinking of possible mods. One thing I will want to do for sure, though perhaps not until after winter storage, is to switch out the pipes for something a bit smaller and bit louder.

    I am sort of a goldilocks when it comes to sound -- not too hard, not too soft. I'd like something a bit louder/throatier than stock, but not something too loud. So I am interested in opinions from anyone who has or has heard in person any of the following -- where would they fit on the scale of "stock to super-loud"? Some have various models I know, so feel free to stipulate.

    I have watched many videos I should say, which are helpful for sure, but hard to know how true to life the sound is. Thanks!

    Main options seem to be:
    Guzzitech (really like the GP Megs)
    Agostini (shorty)
    Mistral
    Zard
    Baak

    Again, looking for something in the middle probably, throaty and cool sounding, without being ear-busting.

    Oh, and I should say, feel free to factor in baffles or no-baffles. I suspect what I am looking for is one of those above but with baffles...

    I fitted a set of the Agostini mufflers purchased through GT to Racer, these:

    476239-3319-thickbox.jpg

    With the db-killers in, they make a lovely, deep sound with a little bit of the NASCAR stock car edge when you rev them and are not overly loud. I wouldn't run them without the db-killers: they'd become too loud. AND they're FAR lighter than the stock mufflers, you can feel this immediately when you ride. The bike becomes less tail -heavy and loses a little bit of propensity to wallow over undulating pavement; it also turns more crisply without the sensation of the tail wagging.

    I'm sure they make a set just like them for the Anniversario model with the right color and hangers.

    The GuzziTech GP Megs are very nice looking; especially as shown in the Store on the Anniversario. You can't go wrong with those.
    However, I would hands-down recommend the GuzziTech 2>1 system.

    I have the GT 2>1 on my bike, and the sound is wonderful. It is louder than stock, louder than many other aftermarket slip-ons, but it is by no means 'super-loud' or 'ear-busting'.

    I have not heard the 2>1 on a V7 III. It's very pleasant on a V7 / V7 II. It could be louder on a V7 III.
    My exhaust became noticeably louder when I switched from the stock 2V Heron heads to the GT 4V heads - but that's to be expected: more flow = more sound.
    Since the V7 III 2V hemi heads seem to be more efficient than the traditional 2V Herons, my guess would be that the 2>1 on a V7 III would be right at the limits of what you consider "Loud", without crossing over to the realm of "LOUD!!!" ;)

    No. You can't tell what the exhausts really sound like from YouTube videos, so this is a good question to ask.

    FWIW - I would not even consider the BAAK shortie system. That one definitely falls into the " T O O _ L O U D !!!!! " category

    Thanks very much, I appreciate all this good info. And I will add to the list of possibles the GT 2 to 1.

    Curious though that you would put the Baak pipes on the LOUD end of the spectrum, my impression being that they'd be somewhere in the middle. Though of course just based on videos and the description Baak gives on their site: "This line isn't a vulgar noise absorption part, it includes exhaust baffles that will provide a deeper sound without damaging the bike's performances. The sound provided is reasonably lound (less than 100 Db), and there is no resonance." Have you heard them in person..? In any case, not sure I like how they'd look on the Anniversario..

    It really is nearly impossible to gauge the quality and volume of exhaust sound from a video... :D

    No. I have not heard them in person.

    There is someone who posted on the GT V7/V9 Forum about the BAAK pipes. (Someone in Las Vegas, maybe???)
    Anyway, I remember him saying that they are VERY loud.
    Probably best to find the thread and shoot him a message if you really like the BAAK pipes.

    I think he also posted a video or two of the BAAK pipes on his V7.

    Ah yes, this thread was very helpful. I think I will probably knock the Baak off the list. The guy does say they are very loud, louder than the video makes it seem. Also, I think that extra short style looks good on the Racer but may not on the Anniversario.. it's not clear to me if the GT megs have removable baffles/db killers or not, but I will check with Todd and find out if I get serious about them. They do seem like a very good option.

    I'm pleased with the Mistral shorty's. Threads on exhaust, tire, oil, are very subjective. Of course we all love the one we spent our hard earned on, to do otherwise would be blasphemy.

    A video does not do justice but here is my bike with the Guzzitech 2 into 1 pipes. I also bought the stubby muffler that is much louder but it just sits in a drawer now. But with either muffler they are not Harley loud. Love the sound and look of my setup.

    I picked the Agostini mufflers on two/three counts:
    • I was familiar with them used on other Moto Guzzis; I liked the sound they made.
    • The more traditional, longer upswept shape appeals to me more than the (likely more efficient) shorty look or 2->1 look.
    • I felt confident that there are enough of them around that a good map should be quite doable with them.
    They're a little shorter than the OEM V7III Racer mufflers: they look just right, to my eye. The two of them together in the shipping box weigh less than ONE of the OEM mufflers, which means a lot in terms of the bike's handling dynamics. And I love the way they sound (dB-killers in; I suspect that with dB-killers out, they'd be louder than I prefer).

    Racer runs very well with both GT's dedicated map for them as well as with GT's customized map for the OEM mufflers. (I haven't tried them with the OEM map.) There are some differences between the running behavior with the two maps; I'm working with GT to see if a slightly tweaked combination of the two maps might produce an even better end result for my personal predilections. But I'm delighted with them even as is. :D

    Thanks for the post.
    I have a video online here on the RentAGuzzi V7/820-R with the 2>1 pipe and GP meg. It is far quieter than the 2>1 with 12" muffler for the V7 I-II I offering, simply because it's a ~18" muffler vs. 12".

    The GT-Rx/GTM GP Megs have non-removable db-killers by default, as the sound is about perfect with them in... a touch on the louder side as opposed to the competition with their db-killers in. I can and have built some by special order without db-killers for the few that have wanted them loud.

    I will again add, the reason I created the GT-Rx exhaust line, is that I tired of constantly repairing and replacing all of the big name brands. If you ride often, consider this fact as the others will fail in time, i.e. bracket welds, rivet cracks around the muffler bodies, etc.

    Thanks for chiming in Todd. Good to get this info. I am thinking that your GP Megs w/built in db-killers will be just the thing for my Anniversario. But I am just about out of riding season here, and have not yet even reached my first service yet. So probably will wait until spring (March or so) before doing modifications. But sooner or later, I will be in touch -- not only about the exhaust but no doubt other things as well!

    Winter in the perfect time to do any mods. Park the bike in the living room and pick away at it (still can't believe my wife was ok with that).

    My first wife & I both enjoyed riding & building bikes & small block Chevy's.
    It was not unusual for a Guzzi or a BSA to be parked in the house & a 327 Chev engine in various stages of being built.

    It was always a giggle when we met new people & I would hear her tell them:
    "Our house is decorated in Early American with Italian accents".
    More fun when they came to visit.

    Unfortunately I have no garage, no driveway, and a tiny house, so my bikes go into winter storage for two and a half months or so. Otherwise several times a year a snow plow would be dumping a couple feet onto my new Anniversario...

    I'm still waiting for Todd's 2>2 system for the V7iii. Hope it's coming soon.
