My car has SLP LM1 catback and o/r Prochamber with weld in cats (thanks Mr. Officer). I want something new...I think. I've listened to dozens of exhaust clips and I think I might want the Atak cb. Is it very similar to the LM1? Which is louder? Similar tone, quality, etc...? I know many don't like the sound of the LM1 but I don't have a problem with it. Perhaps I'd like something a bit more...refined, though. In that case I'm not sure the Atak is the best choice?
