NoterminatorSLP is the loudest. I had them on my 2011 GT. They are in as fuck. Just ask Tbapp, Amberssixxer, Baddmojo, Eddie, or anyone else that heard it lol.
slappayisn't that more of a muscle car? he wants full out race car lol
NoterminatorWithout changing the mid-pipe to an X instead of the stock H, it's still going to be deep. Change the H to an X and slap on them SLP's and he will have what he wants. Nothing is louder than the SLP's. All they are is a set of straight pipes. No mufflers, just resonators.
slappayi tried he doesn't like it he has a x pipe and flow master american thunder on it already. He wants JBA long tube headers, shorty catted x pipe and borla s type mufflers
NoterminatorBorla Stingers are not a race sound. I've had them on my 02 and my 2006. They are very deep. SLP's are much much louder and more race car like in comparison. If he don't like them then he won't like Borla if he wants a raspy race car like sound.
