The MBRP XP Series Exhaust Systems make big horsepower and torque gains with these high flow 4" smooth mandrel bent exhaust systems. Made of 100% T-409 stainless steel, these systems offer the greatest added value when considering all benefits and features. Each system is a direct bolt on application and is manufactured as a full 4" system, including a high quality seamless, polished stainless, straight thru high-flow muffler.

MBRP's massive 5" exhaust systems are now available in the T-409 Stainless Steel XP Series!! These mandrel-bent systems are designed to do one thing: move insane amounts of air out of the engine to create power and sound like nothing else on the market!

High flow is the key to making power on diesels and these MBRP 4" & 5" systems deliver high flow. Includes all necessary exhaust components, instructions and hardware. Lower EGT (exhaust gas temperature), improved fuel economy along with more towing power are just some of the added benefits of having this system installed on your truck. MBRP Exhaust systems are highly recommended on trucks that are utilizing a performance module, programmer or chip and running an upgraded air intake system, to keep EGT's down. Comes with a Lifetime Warranty from MBRP Performance Exhaust.

All 4" systems include an Angled, Rolled-End, Stainless Steel Polished Tip. All 5" systems do NOT include tip. MBRP Stainless Steel Exhaust Tips sold separately. Choose a 6" tip for a 5" system.
