People say the RB motors sound good open like that. I already don’t have a cat and I’m 3" all the way. The problem right now is the test pipe and other exhaust flanges are scraping on everything. What I’d like to do is get some 3" stainless steel and a v-band flange/clamp and extend my downpipe to my cat-back and use the v-band flange for a lower profile connection.
I would do open 3" all the way back but that would be a little louder and don’t want to deal with the po-po
