Ok, so I'm thinking on going with a Mac o/r h. Question is, what would sound better with my SLP 1 catback; o/r h or the prochamber? And is there a difference between the black coated ones compared to the aluminum ones?

 

i cant tell you this i had that setup with an h-pipe it was filthy loud. Pretty much anything other then a stock mid pipe with the SLP is raspy as **** and sounds like crap if you ask me. You'll see what i mean later. I would say prochamnber though as its a bit quieter then a x or h will be.

 

yeah the h with the LM1 is damn loud, My roommate has that and you can hear him from a mile a way or more and it doesn't sound very good. SLP is just loud thats alll nothing else

 

I know mac h pipe and flowmasters sound mean. The black is a high temp coating, that's all and it'll stay black and not rust like most h pipes. i guess the SLP was killing the healthy h pipe sound....

 

I've thought about going with the LM2 style mufflers instead. I want the o/r h for the deeper tone. Wonder what would the LM2 and o/r h would sound like?
