So I recently did the 2 1/4" pipe with the high flow cat to the 2 1/4" inlet of the muffler, my exhaust used to sound deep and extremely mean. Now that I did the full pipe/high flow cat, it sounds like one of those **** *** ricers, is the only way to eliminate that sound to go back to stock pipe, or is there a way to do it without removing it??

 

Add a decent sized resonator or two.

 

also you can get a greddy evo2 muffler. one of that full mufflers not just one that you can see right through.

 

Add a resonator and you'll be good. I'm running 2.5in piping, a vibrant ultra-quiet resonator, and a straight through ES Tuning Systems muffler. No rasp at all and it sounds amazing. It's like $90 on clubRSX

 

I appreciate the input and will deff look into a resonator
