Just put a 5" Turbo back to Dual 4's Flo Pro on my 600.

Way Too loud...

As a fix the Muffler place suggested putting a Twister in ahead of the muffler to quiet it down..

Does this sound right to anyone, or does it just sound goofy to me

Would like to know about the Aeroturbine but do they make it for a 5" with duals?

Has anybody dyno'd the 5" flo pro?

 

5" is just loud. Unless you need it because you have twins or need the flow I'd replace the 5" section with 4". Most 5" duals I've seen are custom, dont think there are any kits.
