For anyone looking for an alternative muffler for the MVVS or Evo 58, Bill Morrison makes semi-custom mufflers that are cheaper than the "name" mufflers, and less restrictive. He'll even modifly the can size for you. Here's a picture below of one on an MVVS 58. They run from $75-$100 depending on whether you need the header or not. His e-mail is: [email protected]

BTW, I am in no way affiliated with Bill, I was just looking for an alternative for the MVVS 58 that would be less restrictive so I wouldn't have to use an in-fuse can, and I ran across his mufflers. I still haven't made my mind up whether to go to the trouble of installing a canister(which I already have) or go with one of Bill's mufflers.
