I have headers, off-road H-Pipe and flowermaster American thunders and the car is just too loud..I get the dreaded 2k drone and want to get a quieter exhaust system..does anyone make a system that I can bolt right on to the H-pipe...I want to replace the tail pipes too..I know Flowmaster makes a 3-chamber from the H-pipe back but I dont know if that will be quiet enough..
