So no, you're wrong.
shutup. unless your cats were clogged or you're talking about one of the turbo merkurs, you didn't gain 20-30hp. People dont even gain that much on NA V8s with cut outs/dumps over full exhaust systems.
And unless you show me dynoed proof, I don't believe it at all. I had a 4cyl and drove it around for awhile with nothing past the testpipe. All it did was sound insanely loud, and go the same no-where that it went previously
You probably just thought it was faster because of all the noise it made.
