Muffler contains an internal H-Pipe for increased performance and improved sound. 140638BC is a full True Dual, split rear exit, Cat-Back™ system with 4" black chrome on T-304 stainless steel tips. Using BORLA® Stainless Steel Polish p# 21461 is NOT recommended with these black chrome tips. We suggest cleaning these black chrome on T-304 stainless steel tips with hot water and a microfiber cloth. A system with bright chrome on T304 stainless steel tips is also available. This system gives the Tundra a great look, pure performance V-8 growl and a nice performance kick. The full dual system even weighs less than the factory single system, thanks to the lightweight T-304 stainless steel fabrication and, not surprisingly, out flows the stock exhaust. BORLA® Cat-Back™ and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA® Sound of Power respected by motoring enthusiasts everywhere.

Each system is built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.

Best of all, BORLA® stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
