The guy at the exhaust shop said that removing the resonator should help open up the exhaust and I should be able to tell. I thought eh, he's feeding me a line of BS. Just cruising around playing a little I really didn't feel any difference in power, but when I got out on the road home I got behind a 10 wheeler grain truck leaking corn (ha, imagine that in Indiana this time of the year) and a car between us. We finally came to a short passing zone and I nailed it, man my car took off like a rocket, better than I think it ever had. Maybe I was just imagining it, but I think it gave it a few more ponies.
