I wanted to get a custom exhaust done in my car, I have an h22 swap I'm doing in about 3 wks, and I wanted a good custom exhaust. I was thinking along th lines of 2 1/4" piping with a good deep non-raspy muffler. I'm gonna have a hi-flo cat to eleiminate some noise. I had a test pipe and it was too loud for me. I'm looking for something that isn't too loud, but is very deep. I like the sound that the HKS Hi-Power exhaust makes on thier wrx......http://hksusa.com/content/misc1759.wmv
