Big Bore & Stoker Engine Kits, Cranks, and Pistons


Is your exhaust limiting your small engine build? NR Racing has the mufflers, headers and exhaust pipes you need to build a free flowing exhaust. We carry stock replacement components, as well as vehicle brackets and braces to keep everything in place. We offer three options for custom and high performance applications. Our build your own exhaust kits have pipe sets that can be clamped or welded together as needed to fit your installation, no matter what your engine is powering. This is usually the best option for karts. We also have individual parts you can buy to build your exhaust, including headers, clamps and high flow mufflers. For common builds, like snowmobiles, boats and drag bikes, we have preassembled exhaust systems that fit most applications.
