MBRP 4 Inch Cat Back Exhaust System

The MBRP 4 Inch Cat Back Exhaust System is a bolt-on performance exhaust upgrade. It replaces the restrictive factory piping behind the catalytic converter with larger 4 inch tubing. The result is a freer-flowing cat-back system with a deeper, more aggressive exhaust note. This single side exit design is built to MBRP's Performance Series standards.

Key Features:

• 4 inch cat-back design: Larger-diameter tubing than stock improves exhaust flow, and the system keeps the factory catalytic converter in place.
• Single side exit: Routes exhaust out the side of the vehicle for a clean look and a distinctive sound.
• Aluminized steel construction: Heavy-duty aluminized steel offers a value-focused alternative to stainless. It suits dry climates best.
• Mandrel-bent tubing: Smooth bends with no rippling help keep exhaust flow efficient.
• Fully sealed tubing: Sealed seams are designed to improve rust resistance and extend system life.
• Bolt-on installation: Designed to install with common hand tools, and no welding is needed.
• Muffler-equipped: A performance muffler delivers MBRP's signature tone.
• 1-year warranty: Performance Series part numbers ending in P carry a 1-year warranty.

MBRP is a well-known name in truck and performance exhaust, and its systems are developed with dyno testing. This cat-back exhaust system is for owners who want better flow, improved sound and a straightforward installation at a sensible price.
