Message that's what's causing the drone. I imagine if the resonators were on the X/H pipe section, it wouldn't be as bad as the sound would already be behind you.

I went under the recommendations I've read that to quiet down the exhaust, start at the mid pipes, and if that isn't enough, do the X/H pipe. I had 2 reasons for getting the mid resonators. 1. IF a cop happens to be an ass and looks underneath, I can claim they're high flow cats. 2. I remember having some rasp on the higher RPM's w/ my old Greddy Power Extreme on my old TT. I didn't want ANY rasp at high RPM's.
