droning is your exhaust NOT test pipes. and rattling is cheap resonated test pipes which say remove rasp and drone. which they dont do either. just test pipes that a pipe nothing more is the way to go. ive been in the VQ area for a very long time. built them up and torn them down. 650whp+ i know it all...

agree, agree, and agree.
Nothing's wrong with TP. I ran custom headerback on my G35 with Headers and mine doesn't have that much rasp compared to others with HFC + catback. It's all in the design of the exhaust.
X02 aren't bad exhaust. They copied HKS design because it works (reduce drone and rasp). HKS = higher pitch while X02 = deeper tone. X02's welds are also good. Nothing's bad about them. If anything, it's their mufflers and their quality vs HKS.
Can't go wrong with either.
