get a regular performance muffler like a turbo muffler or a thrush, you know those cheapies at pepboys to try out. or spend some dough on a nice stainless magnaflow. im not a huge fan of flowmaster, had both magnas and flowmasters on my mustang and the flowmasters where raspy and tinny while the magnas where deep low and very refined in sound. im sure ill be replacing my thrush with a magnaflow.cool cool thanks ah any suggestions on mufflers ??????
