Part #: IS - S2NRMD - S14. This is an interchangeable non - resonated mid - section designed for ISR Performance's SERIES II exhaust systems, specifically for the Nissan 240sx from 1995 to 1998 (S14). Note that this is just the non - resonated mid - section, not a complete exhaust system, and it only works with SERIES II exhaust systems, not older models. ISR Performance's new Series II exhausts have a modular design. This allows you to easily switch between different Series II mid - sections (resonated and non - resonated), as well as the new Series II EP Single, Series II EP Dual, and Series II GT Single rear sections for your specific vehicle chassis. What's in the box: 1 non - resonated mid - section and 1 gasket and hardware pack. All ISR Performance products are for off - road use only and are legal in California only for racing vehicles that are never used, registered, or licensed for highway use.

Using this ISR Performance non - resonated mid - section is quite straightforward. First, make sure your vehicle is a Nissan 240sx from 1995 to 1998 (S14) and it has a Series II exhaust system. If so, you can install the mid - section with the provided gasket and hardware pack. Just follow the normal exhaust installation steps, like lining up the parts and tightening the bolts properly. Remember, this product is only for off - road use. In California, it's only legal for racing vehicles that won't be used on the highway. For maintenance, it's a good idea to check the connections regularly, especially after long drives or rough rides. If you notice any loose parts or damage, fix or replace them right away. Keep the mid - section clean to make it last longer.
