From simple axle back exhaust systems to full cat back systems which include over axle piping with mandrel bent tubing, Magnaflow has what you need.

Street Magnaflow systems feature 3" pipes with an oval muffler and a 4 inch tip. Magnaflow Street systems will increase sound slightly from stock without excessive sound levels when combined with the stock headers and catalytic converters. With header systems and high flow cat systems Magnaflow Street Systems come alive with sound but never become overly loud with an muscular tone that is sure to please without intrusive sound or resonance inside the vehicle.

Magnaflow Competition systems feature a round style muffler with 4" inch tip. Magnaflow Competition systems feature a substantially more aggressive sound than street Magnaflow systems. Want people to know you are coming? Magnaflow Competition systems are the way to go.

Available in Cat Back and Axle Back configurations.

Highly recommend
I installed the street cat back and I cant stop sitting in the driveway and listening to the sound. Very mellow cruising at 80mph on interstate 5 here in southern California but when you put the hammer down the exhaust really lets them now your coming. Deep, throaty, strong sound that will leave you with a permanent smile on your face every time you start it up. The wieght of the mufflers is incredibly light when compared to the stock ones, not sure how much lighter but I would guess they are 10 pounds lighter than stock. Taking 20 pounds off the rear overhang has to be good for something.

Great sound and performance combo!!
I ordered the Magnaflow Street Axle back and i have nothing but great things to say about how awesome it is. Its perfect for the person who enjoys a nice smooth sound. At cruising its mellow, but as soon as you roll into it it screams.
