Re: no cats vs. stock cats vs. high flow cats for my application?
I had 3" high flow cats and belanger cat back on my 94. The car was really loud. I couldn't have a conversation in it if I was moving at all. It sounded good, but really loud. I did a sound level test on it to see how illegal it was. By california law, the car must measure 95 dBA from 30" away from the pipe while the car slowly revs from 2,000 to 5,000 while out of gear. It hit 117 dBA before 4,000.
