The Nissan 370Z exhaust system as it comes from the factory has a pleasing tone and decent performance. If you want a little more and are looking for something that will free up some extra power and sound a little less restrained, then a cat back exhaust is a great idea. Upgrading your Nissan 370Z exhaust system to one of the quality systems that we offer will provide respectable power increases and sound great while doing it. Many of the systems that we offer are 95db or under and sound aggressive without being unnecessarily loud. Check out the product descriptions and pictures, or contact us for help picking out the right system for your 370Z.
