Also what did you do for exhaust? I'm guessing you'll keep your magnaflow setup but what the midpipe? Did the kit include a new one?
I currently have Lethal's 3" offroad H pipe with their resonator delete OTA pipes. Sure, it necks down to 2.75" @ the back of the midpipe, but I plan on doing exhaust cutouts for racing. The kit does not include anything exhaust past the downpipe because it will bolt up to anything factory or aftermarket made to fit the factory header.
