If you could only do one delete which would it be and why? I have heard from some the muffler is most restrictive get rid of it, other say cat is, does anyone here have the correct answer. Which one will sound better, which one will perform better.
Definately delete both. I was concerned too before I straight piped my exhaust and didnt want to delete the cat. My friend convinced me to delete both and Im so glad I did. Not only does it sound really nice (not too loud but loud enough to turn heads) my egt's also dropped.
