The Inside Story on MagnaFlow Mufflers!
The WideOpen™ performance mufflers 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, regarless 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 systemwide high-flow.
