The Pro Racer X-Tube S Spec is the ultimate performance catback exhaust system. It starts at but does not include the header. This exhaust will give your 350Z an incredible power gain with an amazing deep bass sound roar. The X Tube dual pipes expand exhaust volume and increase exhaust flow rate. Dynamic exhaust note, torque gain, and smoother exhaust current are achieved by jointing dual tubes. Dont be stuck with a stock single pipe layout that causes unstable exhaust pressure.
Piping 2.38-2.75 inches... Tip 4-6 inches. Sizes depend on turbo application.
