It's easy to do what I did and put a chrome exhaust tip on it, then stuff a glass pack muffler in it. I've got one tip that has a 12" muffler in it, and another that has an 18". The 12" is just a little too loud but the 18" sounds great. That's an 20" body, the overall length is around 24". You can get all kinds of tips in different sizes and lengths, and either turn out, slash cut, rolled edge, etc.
Or get a SuperTrapp and stick that on there. For any of them all you have to do is make up a connector pipe to get you from the head pipes to the muffler.
