Polar Diesel Exhaust & Performance

Polar Diesel exhaust parts are built for diesel pickups. The page is mostly mufflers, with a smaller group of complete exhaust systems.

Systems come in stainless steel with a muffler or without one, and in four-inch and five-inch pipe sizes. Titles name the engine, such as the Duramax in Silverado and Sierra HD trucks and the Cummins in Ram 2500 pickups. A downpipe is also listed for a Duramax engine, and a DPF-back system for the Jeep Gladiator diesel.

Mufflers and silencers are sold by inlet size. Universal four-inch and five-inch silencers fit custom builds, so check the pipe diameter on your truck or your planned system before you buy.

The vehicle list names Ram 2500, Jeep Gladiator, Chevrolet Colorado and GMC Canyon, and the titles also refer to the Titan and Silverado and Sierra HD. Exhaust parts are matched by engine and year range, so check both on the product page.

For a quieter or louder truck, the choice of muffler matters, and a system without a muffler is the loudest option. See the full exhaust and performance range for other brands and parts.
