I second that as well.... I have a buddy with your exact setup minus brakes, diff lockdown kit and a couple other things but is on RB's AR downpipes, and cut the secondaries out and placed the "quiet vibrant resonators" (they have a super quiet, quiet ect..) and straight pipes all the way back with muffler delete...He has a very very slight rasp at 2200-2400rpm's but nothing like I just heard. I really think it makes a difference where they are placed for sound quality and where the secondaries go is kinda a perfect place.

I was an idiot and did the Akropovic setup downpipes back which was a WAIST of money IMHO.. Dont get me wrong, it does sound good but not for the money I paid. I can do exactly what you did or my buddy actually and get similar results without the money I spent :-/

Oh well lesson learned
