the exhaust on my car is pacesetter long tubes no cats true duals 3" to the x pipe and 2.5" from the x pipe to keep some back preshure its an over axle system with 2 magnaflow race series mufflers the round ones not oval i think the oval ones are a little quieter. next time i have the car racked i will try to get some good shots of this system but its all custom made by rick at synergy motersports in newark ca. its not cheap you need a panhard relocateion kit just to get it over the axle and that alone is $250 i went v band on the headers also every thing will run you about 1600 give or take 200 depending on the mufflers. i did this set up because nobody has it and i get the same ????? all the time "WHAT IS THAT EXHAUST SOUNDS BAD A$$" thanks for the good comments and thares your answer i would recomend true duals on any f-body the video does no justice for the true sound.
