I recently installed the SLP Catback exhaust on my 03 Extended Cab 5.3L and it is barely louder then stock. I want a complete bolt in kit that is loud, something comparable to the SLP Loud Mouth exhaust on the F-Bodys. Anyone suggestions, thanks.

 

corsa is f*cking loud....but wait mine was with no cats.....never ran it with cats,
if u want a loud catback.....i'll sell u my homemade cat-back......stock exhaust with no muffler

 

Just change mufflers to a loud type, or remove the muffler.

 

h-pipe to 2 flowcrap 40's then pro dumps. Louder than anyother exhaust on a truck around me. Failed the town noise ordinance @ 1400 rpms

 

True Duals.... With Cut outs.....

 

Just put a cutout im sure you'll like it.

 

DITTO I have true duals with QTEC's and it is so fu*^ing loud that it it hard to hear someone talking right next to you when the pedal is mashed!!

 

If you want a loud sound just by a SLP loud mouth resonater. Loud as hell and sounds real good.

 

While not as loud as an exhaust with cutouts, my Bassani is really deep sounding and makes quite the rumble. Bugs the neighbors at WOT on a cool morning!

just put a 10 series flow dumped wit no cats it will raise the dead
