MBRP S5018409 Cat Back Dual Split Side Exit Exhaust System T409 Stainless Steel

The MBRP S5018409 Armor Plus Series Cat-Back Exhaust System delivers enhanced performance and an aggressive exhaust tone for 2003-2007 Chevrolet Silverado and GMC Sierra 1500 trucks. This dual split side exit system is engineered from corrosion-resistant T409 stainless steel with mandrel-bent tubing to maximize exhaust flow and reduce back pressure, allowing your engine to breathe more efficiently for improved power and throttle response.

Key Features:

• 2.5-inch diameter mandrel-bent T409 stainless steel tubing for optimal exhaust flow
• Dual split side exit configuration with mirror-polished 3.5-inch outer diameter tips
• Sixteen gauge T409 stainless steel construction resists penetrating rust and corrosion
• Bolt-on installation for straightforward fitment
• Enhanced exhaust tone without excessive drone
• Backed by MBRP's lifetime warranty against manufacturing defects

Performance Benefits:

Mandrel bending ensures smooth, ripple-free bends throughout the exhaust path, eliminating flow restrictions found in crush-bent systems. This superior construction allows exhaust gases to exit more efficiently, reducing exhaust gas temperatures and improving engine performance. The result is better throttle response, potential fuel economy gains, and a deeper, more aggressive exhaust note that sets your truck apart.

Durable Construction:

T409 stainless steel offers excellent value and durability for most driving conditions. The material is easy to maintain and provides superior corrosion resistance compared to aluminized steel. While T409 stainless steel resists penetrating rust effectively, heavy salt exposure and harsh winter road treatments may accelerate surface oxidation over time. The system is designed for extended cab and crew cab short box configurations with 4.8L or 5.3L V8 engines.

This complete cat-back system includes all necessary hardware and components for a professional installation. The MBRP Armor Plus Series represents an exceptional balance of performance, sound, durability, and value for GM truck enthusiasts.
