I have a MAC O/R H pipe, SLP LM1 cat-back. I was wondering how they compare to the Flowmaster 40 series. I've seen all the exhaust chips on the net, they're are only as loud as what ever my speaker volume is. Would you consider the LM1's to be the loudest out there?

I just want to know if anyone has any personal experience with this. A 2002 Rouche came into my job with shorty headers and an o/r h pipe with some kind of side exit magnaflow cat-back, and it was very quiet compaired to my exhaust, I'd love my exhaust to be that quiet.

Haha if you wanted quiet, you made a bad decision with the LM1. Probably one of the loudest out there. The LM2's sound similar, but not as loud.

lol I know right! As a cat-back, they were quiet though, once I put the o/r pipe on, they're much louder. =)

I had 40's on before my SLP's and the slp's are way louder. Dont get me wrong the 40's were loud too but with a deeper rumble.
