It sounds mean and has a nice rumble on the outside, but it's just has too much resonance from 1,400 rpms to 1,600 rpms and I do a lot of city driving so it's starting to bug me. I've read that if you cut the last bend off the tailipipe it...

    Possible to get stock muffler put back on?

    I put a 3" thrush welded on my 96 RCSB 305 and liked it until it broke in and now it's wayy too loud for my liking.

    Best QUIET/stock muffler?

    So what did you end up doing? And carquest sells oem style tailpipes for around $30. Did you even inquire at an auto parts store for an oem muffler?
