MagnaFlow Exhaust Systems

Competition Series Stainless Steel Exhaust System by MagnaFlow®. The Competition Series is designed for customers seeking maximum performance, reduced mass and an aggressive exhaust note that demands attention. These systems may not comply with all local or federal noise requirements.


  • Aggressive Sound
  • Delivers More Horsepower
  • Delivers An Aggressive Race Engine Exhaust Note
  • Lifetime Warranty – Lasting For The Time You Own The Vehicle

The stainless steel pipes in a MagnaFlow System are mandrel bent, keeping their shape through the bends to avoid obstructions to the gas flow. The gases are led into the free-flow mufflers with smooth necks and a straight-through, perforated stainless steel tuning pipe. The pipe is wrapped in a stainless mesh wrap and surrounded by tightly packed acoustical fiber in a lap-joint welded stainless steel body. The muffler is finely tuned to dampen irritating pitch notes and to deliver that roaring race engine tone that is so characteristic of MagnaFlow competition exhausts. The quality materials and the tight packing of the acoustical material ensure long life and no sound degradation over time.

The careful free-flow design, the first class workmanship and the attention to detail in both design and fabrication combine to achieve maximum performance and a true racing engine sound.

Get your MagnaFlow Competition Series system today and outperform your competition at the next race event.

No other brand has managed to fulfill the demands auto enthusiasts have on their exhaust systems, while still complying with emission standards, as MagnaFlow has. The product line is steadily expanding, introducing new, cutting edge technologies and designs. MagnaFlow is the leader in exhaust system design and the company is determined to stay in the lead.

MagnaFlow Exhaust Review
Due to how low the vehicle was, I had this installed professionally. The only issue they had is the tips aren't perfectly straight coming out the back. They made many adjustments to get it close but it's not perfect. Other than that it was easy to install and sounds amazing!

Pontiac G8 GT Exhaust System
MagnaFlow Competition Series cat back exhaust arrived days after ordering. Installing system took two hours in my garage. Exhaust looks great from behind the car. Stainless steel and polish mufflers brighten up the underside. Driving my car people stop and look for the sound is deep in tone and aggressive. I can tell it improved the cars performance. I would install the same system on future cars. Neal Yerges MagnaFlow fan.

Axle-back Competition Series
Product looks great with the stainless steel mufflers and big tips, has a great sound, especially on start up and idle. A unique, but not as loud sound with an aggressive tone. However, I ordered the dual mode option and the valves did not close properly but Magnaflow was extremely helpful with this, sending me a new kit.

Sounds Great!
I was looking for a Flowmaster system when I stumbled across this one. It was easy to install and it looks good!. The sound is perfect, loud when dip into the throttle and mellow for crusing.
