Deleting my secondary cats..
Well i deleted my resonator on my E90, and divorced the piping, no x-pipe, i like the sound, Coupe like loud maybe a bit more. More rumble since there is no x-pipe im guessing down low around idle, sounds good.
Tomrrow i am deleting my secondary cats, just wanted to hear some opinions on sound, will it get much louder or even louder at all?
