Actually, folks just call me Trav....

My bikes are all 4 stroke now. But that's a different discussion.

The stocker cats flow great, and there is no reason to change them out for anything bigger, unless you plan on going twin turbo Flycacher. Do you? You plan on a couple of snails under the hood to get away from 'ol Roscoe there Bo Duke?

Probably not.

I know that not only Pacesetter, but Magnaflow and Dynomax also make them. Having to massively modify them to fit your X, then getting absolutely ZERO benefit from them because you don't flow any better, well, that's just pure stupidity!

You wanted an answer, and now you're crying when someone tells you that it's a bad idea. That's tough. Really, get over it.
