I want to purchase a cat back finally and can’t decide whether I want borla or mbrp. I read about leaks and need for tips with mbrp, mbrp sounds louder but folks all seem to need tips and it’s not ThT much louder than stock from what I’ve heard. The borla seems louder for sure and I know there will be some drone but I think I like the aggressiveness over the borla with stock tips over the mild but great mbrp sound . Any borla regrets? After selling my Corsa equipped c6 I need noise!!! Good quality noise lol
