I just installed the NISMO system on my 350. After reviewing all of you guys' info & researching exhaust systems for about a month, I figured it was time to make the purchase. I've gotta say this is really a very nice setup. Fits great, looks perfect, sounds excellent & the performance increase is very noticable. I got a great deal on it too, through the dealership. I met the owner several months ago & he said if you ever need to purchase anything for the Z, he'd sell it to me at their cost. Not sure if I got that exact "cost" price, but at $850, I thought that was a deal, plus it's still under warranty. WOW, I love that sound, too! Powerful sounding when you want it, & comfortable sound when you're cruising. The best of both worlds. Thanks again for all of your opinions & knowledge.

 

If you like the stock sound, with better performance and slightly louder get the BORLA. Great quality, 1million warranty. If you want your z to sound like a 4cyl Honday civic, get the Injen.
