Depends on budget buddy. Personally I had the ARK dual Grip on my 350z and now on my Nismo and wouldn't have anything else. Sounds like a TVR, looks awesome with no rasp. But it expensive. PM Chris at Tarmac for prices and options. The stock Nismo exhaust can hardly be heard and really doesn't do the car justice. Most Nismo owners change them as their first mod.
