Where were you when I had my Tanabe with a Motordyne Res Y pipe?
I have an AAM S-Line midpipe and axle back setup that is quiet, it doesn't drone. At least not from what I can tell, and I have resonated TP's as well. Let me know. We would have to act quickly because I'm rolling out the door for a deployment. Send me a PM if you're interested!
