I agree! I also have no muffs and an X pipe on both my rides. One has Tri-y with high flow cats. The other with stock manifolds and stock cats. Tri-y and cats made things MUCH louder. I have gotten many complements on how good my loud and raspy car sounds.I can tell you with mine even straight stock headers and cats with NO exhaust whatsoever didnt seem very loud or mean to me...however I can tell you that if you do headers&high flow cats its MUCH nicer and how a car with SS in its name should be! My dad even commented once we had test drove it around that it reminded him of the exhaust sound of an old muscle car he used to have in the 70s!
...Also Clear Image Auto Gen II Tri-Y headers and cats FTW!!! Pricey but best out there IMHO
