All MagnaFlow cat-back systems feature fast-flowing mandrel-bent stainless steel tubing, a straight-through MagnaFlow Performance Muffler and a polished stainless steel Magnaflow tip. Magnflow cat-back systems are designed to increase horsepower, torque and gas mileage, they also bolt directly onto your vehicle.
MagnaFlow Cat-back systems also come in titanium. Titanium MagnaFlow Cat-back systems feature cadmium hardware, weight saving hollow hangers, true straight through design Magnaflow mufflers, and removeable silencers, all finished with a hardcore race look blue'd tip.
If you don't want one of the Magnaflow cat-back systems but want the dual look, MagnaFlow makes Universal Tail Pipes for a variety of applications. They all come with fast-flowing mandrel-bends and bolt directly onto your vehicle. Add two MagnaFlow Universal Tail Pipes for a dual exit exhaust application.
Pipe Diameter and Performance
Use the guide below when calculating pipe size for custom exhaust work. Keep in mind that the goal is to improve exhaust flow. In most cases, just changing the restrictive OEM muffler and replacing it with the same size straight-though, Wide Open Performance MagnaFlow muffler will do the job.
To reduce additional back pressure, the OEM exhaust tubing can be replaced with mandrel-bent tubing of the same size or one size up from the OEM. As a general rule, you can enlarge the pipe diameter of your OEM exhaust system by 1/4" to 1/2" to increase your horsepower. However, any additional increase in pipe diameter is likely to decrease your performance; specifically, low end torque.
