Okay, so two days ago I got my resonator taken out and replace with a clear pipe. The work was quickly and brilliantly crafted, I have Iowa Muffler and Brake to thank for that. Anyway, I just wanted to recommend this mod for anyone who has been thinking about exhaust modifications, but wants to keep it simple, but meaty. The sweet spot, so to speak is 2nd gear, at about 4100 RPMs.
