Yes, they will sound better but not buy a lot. Same tone but a little louder. If you want it a lot louder you may want to look at other options. I went to a single chamber race muffler because dual chambers weren't gettin it done for me. When I get on it, people are hurting their necks turning to look. Haha.

08 GT 5spd
Spectra CAI, Comp Cam Detroit Rockers, Kooks headers w/catted H-pipe, Revolution Automotive dyno tuned, FB430 race mufflers, 3.55s, JLT catch can, BMR Lca's and relo brackets. Prothane motor mounts and sway bar bushings.
20% tint, smoked markers and tail lights w/sequentials. Clear front signal covers, series 3 chin spoiler.
