Show original supplier description
It features 2.50-inch mandrel-bent 409 stainless steel tubing that flows into polished 5-inch T304 stainless steel rolled slash-cut tips. The muffler is a Gibson Superflow design, utilizing a baffled and chambered construction with no internal packing to deliver an aggressive exhaust note while minimizing interior drone. This cat-back system is dyno-proven to increase horsepower by 10-15 HP and torque by 15-20 lb-ft, specifically in the 1,800–3,000 RPM range, providing a noticeable boost in low-end power. Crafted from premium stainless steel, this exhaust is built for durability and to withstand tough conditions. Installation is straightforward, utilizing factory hangers and clamp-on tips, requiring no welding. Gibson backs this exhaust system with a Lifetime Limited Warranty.
