The all - new ISR Performance Series II GT Single exhaust offers a great blend of style and aggression at an affordable price. Crafted from high - quality stainless steel, it uses 3 - inch piping for the mid - pipe and most of the rear section. It then expands to a 5 - inch round muffler with a 4.5 - inch extended tip. With the new Series II construction, it has improved pipe routing to increase ground clearance compared to older models. This means you get a stylish exhaust without sacrificing performance. The extended tip fits well with deeper aftermarket aero bumpers and gives a more aggressive look on stock bumpers. ISR Performance's new Series II exhausts have a modular design. You can easily swap between different Series II mid - sections (resonated and non - resonated) and various rear sections like the Series II EP Single, Series II EP Dual, and Series II GT Single for your specific chassis. What's in the box: 1 GT Single rear section, 1 non - resonated mid - section, and 1 gasket and hardware pack. Note that all ISR Performance products are for off - road use only and are legal in California only for racing vehicles not used on highways.
Using this ISR Performance exhaust is straightforward. First, make sure your vehicle is the Nissan 240sx (S13) from 1989 to 1994. Carefully unpack the box and check that you have all the parts: 1 GT Single rear section, 1 non - resonated mid - section, and 1 gasket and hardware pack. When installing, follow the included instructions. It's important to note that this product is for off - road use only. In California, it's only legal for racing vehicles that won't be used on highways. For maintenance, regularly check the exhaust for any signs of damage or loose parts. You can clean it with a mild soap and water solution to keep it looking good. If you plan to swap the mid - section or rear section in the future, refer to the modular design instructions for a smooth process.
