The B2 Fabrication muffler bypass kit for the 2014-2026 Silverado 1500 and GMC Sierra 1500. Swap out your restrictive stock muffler and tap into a deeper, more aggressive sound wit h a small gain in flow and throttle response. Precision mandrel-bent 409 stainless steel and fixture-built fitment mean it drops right into the factory muffler location. Includes all hardware. Proudly made in the U.S.A. Fits: 2014-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 with the 4.3L V6 or 5.3L V8 and single exhaust, all cab and bed configurations. 2019 note: GM sold two body styles in 2019 — the earlier LD/Limited body and the all-new body. This fits the single-exhaust setup on both; if you have a 2019, match by your truck's body and exhaust. It does not fit dual-exhaust trucks or the 6.2L (for the 6.2L, use this kit). Show more
