Hy, I'm looking for the loudest axle backs or muffler delete pypes for a 2008 gt/cs. What do you guys recommend. We don't want to change the rest of the system.

Thanks,

 

SLP LM if you want pure volume.

 

SLP!! Have yet to hear any A/B only louder.

 

+1 I love mine...

 

i think macs a/b have the best and loudest sound or boomtubes

 

Well of course taking the mufflers off will be the loudest. If you go that route get the pypes muffler delete b/c they are cheaper then the SLPs. Loudest muffler I would have to say is the Macs. Very deep and muscular. honestly you will get used to any a/b and eventually swap midpipes for something o/r.....thats what Im doing this spring

 

SLP LoudMouths!!!

check out the youtube vid in my sig!

 

MAC's sound great! I plan on getting those to replace my SLP's.

 

SLP is what I have. its loud, but not loud enough from the inside. Outside its close to obnoxious.

 

SLP or MAC, you'll get tons of people tell you different ones, but it's pretty much always one of these two.
