This Borla system utilizes the factory transition pipe between the cats and the muffler so that it will fit ALL Cab and Bed configurations. The 140851 Cat-Back by Borla is made to give you the best performance, sound and durability possible. It utilizes high quality T-304 stainless steel, superior to T-409, for durability, mandrel bent pipes for high flow, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. The uniquely designed muffler provides the classic Borla S-Type sound without drone. This system comes with a 5 in. bright chrome on T-304 stainless steel tip. A system with black chrome on T-304 stainless steel is also available. And as you would expect it is covered by the Borla Million Mile Warranty.
