Borla XR-1 Multi-Core 3in Ctr-Ctr Oval 12in x 4.25in x 7.88in Rotary Engine Equipped Racing Muffler

This is the Borla XR-1 Multi-Core racing muffler, part number 400372. It's specifically designed for vehicles equipped with rotary engines, though it can be used in other applications too. Its compact size makes it a great choice when you've got limited space to work with under the car, and the reversible design means you have flexibility during installation. Borla is well-known for their exhaust systems, and this muffler is built with their patented Multicore technology, which is designed to maximize power output. In fact, testing shows these mufflers can actually flow better than a straight piece of pipe.

You'll find this muffler is constructed from T-304 stainless steel, so you don't have to worry about rust. The construction is 100% welded for solid strength, and it uses a high-temperature fiber material for sound control. This is a universal part, recommended for high horsepower applications where you need an exhaust component that can keep up. It's made in the USA, and Borla's XR-1 Raceline products are a popular choice among racers for their balance of sound and power.
