I never lost any power with the RT cat in fact gained a good amount from my butt dyno, however thats coming from a stock Accord cat thats more restrictive then the CLS cat. The RT cat did however give a horrible rasp at ~2500rpm, just for a short time and the rest of the powerband was good but you can imagine how it can get worse especially with no resonators and straight through mufflers. The rasp was Civic bad.

Good thread guys, this is a good read. I would think a test pipe, and one of the biggest resonators you could fit under the car would be the best setup.
