How do Stingers compare to XR-1 race mufflers? Any of you guys heard both to know the difference in sound level? They look similar, but I dont know the difference in flow... I started looking around for a different exhaust setup, cause my H pipe is rusty and ticking (Dan's side exit is tempting), but I dont want it to be like running straight pipes. Its not going to be my daily driver much longer thanks to a promotion I finally received, but I still dont want it to be overwhelming. I do want a nice compact muffler, because I am really tempted to try a side exit design. Ive never really liked tails on our cars for some reason. Anyone have any input on the subject?
