MBRP S5002409 Muffler Bypass Street Profile for 2019-2021 Silverado/Sierra 1500

Vehicle Fitment

• 2019-2021 Chevrolet Silverado 1500 (6.2L V8, models equipped with 2 exhaust valves)
• 2019-2021 GMC Sierra 1500 (6.2L V8, models equipped with 2 exhaust valves)

Fitment Notes

• 6.2L engine only - does not fit 5.3L or any other engine variant in the 2019-2021 Silverado/Sierra 1500 lineup
• Only compatible with trucks equipped with 2 factory exhaust valves - verify valve count before ordering
• Does NOT fit the 2019 Legacy (old body style / K2XX platform) Silverado 1500 or Sierra 1500
• Does NOT fit the 2022+ new body style (T1XX second-generation refresh) Silverado 1500 or Sierra 1500
• No exhaust tip is included - this is a muffler bypass pipe only; no tip is part of this assembly

Features

• Street Profile sound tuning produces a deeper, more assertive exhaust note under throttle while maintaining a composed, non-droning character during cruise - significant improvement over the restrictive factory muffler
• Designed specifically to eliminate the factory adaptive exhaust valve mechanism, which is a known source of rattling and inconsistent driving characteristics on the 2019-2021 6.2L Silverado and Sierra
• 3-inch mandrel-bent T409 stainless steel tubing maximizes exhaust flow and reduces backpressure throughout the bypass section
• Clamp-on installation design requires no welding, cutting, or drilling - uses factory mounting points for a straightforward bolt-on fitment
• T409 stainless steel construction provides strong corrosion resistance and durability suitable for normal to moderately harsh driving conditions
• Armor Plus series designation - MBRP's value-focused stainless steel tier offering the same profile as T304 at a more accessible price point, backed by a Lifetime Warranty
• CAD-matched fit ensures proper alignment with factory exhaust routing and hanger positions on the 2019-2021 T1XX platform
• 45-inch overall length provides complete bypass coverage of the factory muffler section

Product Description

The MBRP S5002409 is a 3-inch Armor Plus muffler bypass pipe purpose-built for the 2019-2021 Chevrolet Silverado 1500 and GMC Sierra 1500 equipped with the 6.2L V8 engine and factory dual exhaust valve configuration. Unlike a full cat-back or axle-back exhaust system, a muffler bypass pipe is a single-pipe replacement that eliminates the factory muffler section entirely, replacing it with a straight-through 3-inch mandrel-bent tube. This approach delivers a dramatic improvement in exhaust sound and flow with a simpler, lower-cost installation - making it one of the most efficient performance upgrades available for this platform. MBRP engineered the S5002409 specifically to address the factory adaptive valve system used on the 2019-2021 6.2L Silverado and Sierra, a known source of valve rattle and inconsistent exhaust behavior that degrades the driving experience over time.

Built from T409 stainless steel under MBRP's Armor Plus series, this bypass pipe delivers durable corrosion resistance for normal to moderately harsh climates and is backed by a Lifetime Warranty. The mandrel-bent 3-inch tubing maintains a consistent internal diameter through all bends, eliminating the flow restriction and turbulence caused by the factory muffler and valve assembly. MBRP's Street Profile tuning shapes the resulting exhaust note to be noticeably deeper and more aggressive under acceleration while staying composed at sustained highway speeds - a balance that suits daily-driven trucks as well as weekend builds. At 45 inches in length, the bypass pipe is sized to match the complete factory muffler section on the T1XX platform body style.

Installation is a straightforward clamp-on process requiring no cutting, welding, or specialized tools, using the factory exhaust hanger locations. It is critical to verify the correct body style and valve count before ordering: this part is engineered for the 2019-2021 T1XX Silverado and Sierra only - it does not fit the 2019 Legacy (K2XX old body style) or the 2022+ new body style refresh, and it is compatible exclusively with 6.2L V8 trucks equipped with 2 factory exhaust valves. No exhaust tip is included with this part number, as the S5002409 is a bypass pipe assembly only. Silverado and Sierra 1500 owners seeking a complete tip-equipped solution should consider pairing this bypass with an appropriate MBRP tip or upgrading to a full MBRP cat-back system.
