Toyota Tundra Cat-Back Exhaust Systems by Magnaflow

The Problem with Exhaust Backpressure!
Factors such as backpressure can cause your vehicle to lose power and could slow down or damage your exhaust due to excess heat retention. MagnaFlow's Cat-Back System features their WideOpen performance mufflers which will greatly reduce backpressure. These mufflers reflect heat and resist corrosion better than cold-rolled steel. They also retain their finish longer, adding to MagnaFlow's long life and clean appearance.

The Inside Story on MagnaFlow Mufflers!
The WideOpen performance cat back exhaust systems feature a stainless steel mesh in the core which warms up quickly to maintain the muffler's optimal temperature for exhaust movement, creating a porous barrier that allows sound vibrations to pass freely into the acoustical absorbing material. Packed between the steel mesh and the steel shell, the acoustical absorbing material will filter out all the harsh exhaust vibrations, giving MagnaFlow it's rich, powerful, performance tone.

Increased Performance through Improved Tubing!
Unlike Louvers with bent-in metal flaps which create turbulence and slow air flow, MagnaFlow's one piece perforated stainless steel tubing lets gasses pass right through without any turbulence or backpressure with absolutely no restrictions. Its mandrel-bent tubing design is maintained throughout the length of the tubing, regardless of the bend. The flow capacity in the bend is the same as the straight-away and will result in no reductions or backpressure. All MagnaFlow system tubing is mandrel-bent to assure system wide high-flow.
