I am going to order this from Kolak soon, i know He also sell highflow precats.
There is definitely a power increase, especially in the higher RPM's. It takes almost half the time to get from 60mph to 90mph and the tires squeal even shortly after shifting into 2nd at WOT from a dead stop. My rear tires are a little worn so the helps too. Even picked up a couple MPG's, and of course the sound is great. Nick said his exhaust put out 15-20hp on the dyno when he tested it years ago. I would highly recommend his setup over over a basic 2.5" catback.
As far as the P0432 code goes, i reset it a few days ago and have been driving for a while and it hasn't appeared yet. All casual driving, no WOT runs. If the code doesn't show up in a few more days, i will start driving harder and going WOT and see if it shows up then.
