Sounds just like a Motordyne for almost half the price! Pairs perfectly with Torqen’s HELMZ Resonated test pipes. It has no drone or rasp at any RPM, when you give it WOT it screams gloriously. I’ve gone through 6 different exhaust setups in my Z33 ownership, this is by far my favorite of all time. I’ll more than likely never change it again. Only one con: The right exit pipe with the resonator rests against the EVAP shield. I removed mine and modified it slightly to solve this.
