Borla XR-1 Multi-Core 4in Ctr-Ctr Round 16in x 6.25in Rotary Engine Equipped Racing Muffler

If you're building a high-horsepower rotary engine for the track, you need an exhaust system that can keep up. This Borla XR-1 Multi-Core racing muffler is designed specifically for those demanding applications, offering a unique solution for rotary-equipped vehicles, though it can be adapted for others. Its patented uninterrupted-flow design and multicore technology mean it actually flows better than a straight pipe, according to Borla's testing, making it a smart choice when every bit of power matters.

Constructed from T-304 austenitic stainless steel, this muffler is built for track-tough durability and will not rust. The 100% welded construction ensures strength, while the high-temperature stainless steel wool packing helps control sound without sacrificing performance. The reversible design offers flexibility during installation, and its compact 6.25-inch round by 16-inch long body is ideal for tight spaces. Borla is known for its exhaust expertise, and this XR-1 muffler represents a solid option for achieving the best balance of sound and power for your racing setup.
