stock exhaust - it's unbelievably quiet! Why?

Cyber370

I can attest to the fact that ARK DTS sounds absolutely incredible driving slow or fast. Best I've ever heard and not obnoxiously loud with stock cats.

The only thing you need to remember is that there are two types. ARK Grip and DTS. The Grip version will not fit a Nismo model without some modification. The DTS fits all versions of 370Z. As to which type is louder or sounds better, no one really knows since they both sound very similar even though they are significantly different in design after the axle. Some say the Grip is slightly louder while others say it's the opposite. Sooo.......it's really subjective. Good luck.
