BORLA 140638 is a 2.25" diameter full True Dual, split rear exit, Cat-Back™ system with single 4" round bright chrome on T-304 stainless steel tips on each tail pipe. A system with black chrome on T-304 stainless steel tips is also available. This system gives the Tundra a great look and a nice performance kick. It delivers the mellow Touring sound with no drone inside the vehicle. The muffler contains an internal H-Pipe for increased performance and improved sound. 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. This BORLA dual system even exhibits better fuel economy numbers which is nice for a big truck. 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,
- BORLA system is True Dual
- Muffler contains an internal X-Pipe
- Oversize box shipping rates apply to this system
