i ran my helix pipes and stillen y pipe, and it was the worst sound ever, before i got the cat back. I was ashamed to drive my car lol!

 

but it is becuase your stillen y-pipe has 3" outlet and your stock exhaust is 2.5", so creating backpressure, therefore making raspy noise? coz i put test pipe with megan y-pipe, CRAZY raspy noise!!!

i wonder if the kinetix y-pipe with 2.5" outlet to stock exhaust which is also 2.5" will eliminate the raspy noise?

anyone have expreience or tried? or any theory to if it will make rasp noise?
