Upgrading vehicle’s exhaust system is a great way to build horsepower, free up trapped torque, and improve upon restrictive factory systems. The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle. The net result is lower auto exhaust backpressure, more horsepower, more torque, and a much better sound.
Package Included:
1 X Axle Back Exhaust Kit in the Picture Above
This product is compatible with:
03-08 Nissan 350Z

Emissions issues

Harsh rasp
-
Full exhaust cost

So i got this because my stock muffler was old and hanging lower and lower every week. 350s come with a 2.5 single then duel at the muffler. I ordered this before i heard what my car sounded like without a muffler. Im very picky about sound so i wanted to be proactively. But my muffler came off before i got this delivered ( takes about a week) i love the sound of my 350 with no muffler its not super load. Its smooth and steady. Think stock but 40% louder. Im going to put this on but it will take some custom work to do so since i didnt buy the other parts of this exshaust system because i was going to jump up to 3in but if it sounds noce i wont. I will update. UPDATE. Had on my car and took them off. I hate the sound. It sounded like a really crappy honda civic.

Description said it was a 2.5″ inlet and outlet, i measured it and turned out to be 2-1/4″ total. I was expecting that at least the dimensions were correct. Don’t waste your money or time!
