At my last local employment facility one of my co-workers had a EF Hatch with a B18b in it. When I took my first look at it I said, "You have a stock exhaust?" and in fact it was, BUT he told me that he had cut 'slots' in it to act like a nice expensive exhaust kit, it was pretty loud, but not too loud. I'm wondering if this does anything to improve performace? Im wondering because its the stock small pipes that it wouldnt do anything. So where are the holes or slots made and does it actually improve anything besides the noise.
Thanks,
Scott
