fastaussie Posted November 17 Posted November 17 anybody opened these up before? is it possible to remove some baffling to let a bit more sound out, incrementally? maybe 30%?
GuzziMoto Posted November 18 Posted November 18 I would think someone would have already responded. But here is my two cents. There is no easy way to "de-baffle" the stock mufflers. In fact, as I recall, if you remove those screws you will find that there is no access to the internals of the stock muffler without cutting it open. That cap is just for looks. Some people have done dumb things like drill out the stock muffler. But the results are not good in my opinion. If you can't swing a decent set of proper mufflers, you can get some cheap generic mufflers and adapt them for less work then it would take to open up the stock mufflers. 4

With the advantage that the stock mufflers remain intact, which is what I would prefer. You never know if you might want to put them back on one day. 2
audiomick Posted November 18 Posted November 18 Thanks for the link @docc After only glancing over the first couple of pages, I feel confirmed in my opinion and @GuzziMoto 's advice to get some after-market mufflers instead of "improving" the standard ones. Butchering the standard mufflers with no way back just doesn't seem right. 2

Yes, George Thorogood, Bad to the Bone. A fellow V11 Sports rider just past by a couple of months ago with his MIVVs. Even when he toggled at low rpm out of the backyards street the sound was amazingly loud. He was ashamed by it himself, but even on the highway it was disturbingly loud for him when in the saddle. The design is quite pretty though, but I guess you do need some volume to damp the noise after all. I purchased a set of EXANs, the originals were crashed a bit when I lost the front-end at the white lines. They do pretty well up to approx 4500-5000rpm after that it is almost like they are saturated and start to sound very loud. I get tired of it when riding for several hours (what I usually do). It is a pitty that the original cans are so extremely heavy. 3
Joe Posted November 19 Posted November 19 (edited) In reality these V11 Sports aren’t faster than most Honda’s. But when you are winding them up the sound emitting from the Mivv’s makes you feel like you’re going to podium in WSB, glorious. Edited November 19 by Joe 2 1 3
Lucky Phil Posted November 20 Posted November 20 (edited) The Mivvs are too small not be loud. You're correct, not enough Volume. My bike runs Agostini straight reverse cone megaphone style which are not overly obnoxious. The other obvious hinderance to lower noise output with sports type absorption mufflers is the lack of an exhaust collector. My RE650 Interceptor has no collector or cross over for it's twin cylinder 650 engine and the aftermarket mufflers I have fitted to it are louder than I like even with the DB killers installed. It has a very distinct crack to the exhaust note with the throttle open quite a bit which is a lot of the time 2 up with only 45 HP at the back wheel to play with.

kalev11 Posted November 20 Posted November 20 Hello guys. Long time no see. I love the MIVV cans. They unfortunately are no longer available. 2 2
po18guy Posted November 20 Posted November 20 Biased in favor of Staintunes. Here is an 1100 Sport with a full system. As we see, this fellow is badly addicted. 4
