Tips: Single Round Rolled Angle-Cut

Muffler contains an internal H-Pipe for increased performance and improved sound.

 140638 is a 2.25" diameter full True Dual, split rear exit, Cat-Back™ system with 4" bright chrome on T-304 stainless steel tips.

A system with black chrome on T-304 stainless steel tips is also available.

This system gives the Tundra a great look, pure performance V-8 growl and a nice performance kick.

It delivers the mellow Touring sound with no drone inside the vehicle.

 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.

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.
