I have a 2003 Gt with a pypes o/r x and a flowmaster catback..i believe its the thunder series, not sure though, it was on the car when i bought it. It sounds ok but it could sound better. I just want to swap out the mufflers. I was listening to different videos on youtube and now i am considering MAC mufflers, LOUD doesnt bother me i live in the woods, loud is good, i just want something that sounds good and has a deeper tone than what i have.
what do ya think?????
