When I got my exhaust installed, they put on the wrong tips. The exhaust is too loud and I'm having them put the stock resonator back on to quiet it down. They got the correct tips in but they said it would get louder with the correct tips since they are a bit bigger. Is that true? I would think it wouldn't. The muffler is under the car in the middle then it splits to my dual tip just before the rear axle.
