Fitment Notes

• Compatible with 4.3L V6 and 5.3L V8 engines only - does not fit the 6.2L V8 or any other engine variant in these model years
• One-piece driveshaft only - does not fit trucks equipped with a two-piece driveshaft; verify driveshaft configuration before ordering
• 2019 fitment applies to the Silverado 1500 Limited and Sierra 1500 Limited (LD - legacy body style) only - does not fit the 2019 new body style (T1XX) Silverado or Sierra 1500
• T409 stainless steel may develop surface rust over time, particularly under wintry road conditions or heavy road salt exposure - surface rust is not covered under warranty

Features

• Street Profile sound tuning delivers a deeper, more assertive exhaust note under throttle while remaining controlled and non-droning at highway cruise - a significant improvement over the factory system without aggressive volume
• Dual side exit configuration routes exhaust out of both sides of the truck simultaneously, delivering a symmetrical, track-inspired rear appearance - the classic performance look for this generation of full-size GM trucks
• Full cat-back design replaces all factory exhaust from the catalytic converter rearward for the maximum flow improvement available in a bolt-on package
• 16-gauge T409 stainless steel construction provides strong corrosion resistance suitable for moderate climates with rain and variable weather, backed by a Lifetime Warranty
• Mandrel-bent 3-inch tubing maintains consistent internal diameter through all bends, reducing backpressure and lowering exhaust gas temperatures versus the factory system
• Dual mirror-polished T304 stainless steel single-wall rolled angle-cut tips (one per side) provide a bright, durable finish at both exits
• Direct bolt-on installation using OEM factory hanger locations - no cutting, welding, or drilling required
• All necessary hardware, clamps, mid-pipe, over-axle pipes, tailpipes, and muffler included for a complete installation

Product Description

The MBRP S5082409 is a 3-inch Armor Plus dual side exit cat-back exhaust system engineered for the 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500, as well as the 2019 Silverado 1500 Limited and Sierra 1500 Limited (LD), equipped with either the 4.3L V6 or 5.3L V8 engine. As a full cat-back system, the S5082409 replaces all factory exhaust from the catalytic converter rearward - including the extension pipe, mid-pipe, muffler, over-axle pipes, and tailpipes - delivering a comprehensive improvement in exhaust flow, reduced backpressure, and lower exhaust gas temperatures. MBRP's Street Profile tuning shapes a deeper, more commanding exhaust note under acceleration while keeping the system composed and non-droning at sustained highway speeds, making it equally suitable for daily commuting and spirited driving.

The dual side exit layout exits behind both rear wheels simultaneously, delivering the symmetrical performance truck aesthetic that has made this style a benchmark for full-size GM truck builds. Each exit is capped with a mirror-polished T304 stainless steel 3.5-inch single-wall rolled angle-cut tip, providing long-lasting brightness at both exits. The system body is built from 16-gauge T409 stainless steel under MBRP's Armor Plus series, offering strong corrosion resistance for moderate to variable climates and backed by a Lifetime Warranty. Buyers should note that T409 steel may develop surface rust under wintry or high-salt conditions - this is a known material characteristic not covered under warranty.

Two critical fitment restrictions must be confirmed before ordering. First, this system is compatible with the 4.3L V6 and 5.3L V8 engines only - it does not fit the 6.2L V8. Second, and critically, this system requires a one-piece driveshaft - it is not compatible with trucks equipped with a two-piece driveshaft. Owners should verify their driveshaft configuration before purchasing. The 2019 fitment covers only the Legacy body style Limited (LD) designation - the all-new 2019 T1XX Silverado and Sierra 1500 are not supported. The S5082409 is backed by MBRP's Lifetime Warranty and is the stainless steel dual side exit upgrade of choice for 2014-2018 Silverado and Sierra 1500 owners seeking proven performance, quality, and that classic split side appearance.
