Features

  • Stainless Steel:  Magnaflow mufflers are constructed of a heavy gauge stainless steel body, end caps, and one piece core deliver long life protection.
  • Fiber Fill Packing:  MagnaFlow mufflers are packed with high tempurature acoustical suppression materaial for maximum resonance and sound absorbtion.
  • Stainless Mesh:  Stainless steel mesh is used on all performance mufflers to provide durability under high temperatures.  The stainless steel mesh material also provides additionals sound absorbtion with no blow out.
  • Wide Open Design:  All MagnaFlow mufflers are a straight through design with no baffles.  The straight through, one piece core offers unrestricted flow and dramatically reduces backpressure and heat. 
  • Stainless Core:  A large diameter, perforated stainless steel core eliminates the flow restrictions of louvered styled cores giving Magnaflow mufflers a performance advantage over competitor's designs. 
  • Lap Joints:  All joints on Magnaflow mufflers are overlapped 1/2" and fully welded to offer leak free quality.  All welded, overlapped joints avoid distortion and cracking.
  • Reversible:  All MagnaFlow mufflers are reversible to allow a custom fit.

MagnaFlow High Performance Muffler Frequently Asked Questions

Question: Does MagnaFlow make a muffler for a specific car?
Answer: MagnaFlow mufflers are universal and can be installed on virtually any car using basic mechanical knowledge.  Look at our Cat-Back Exhaust Systems for what muffler sizes we use on our cat-back exhaust systems for cars and trucks, so that you can get a good idea of what muffler is right for your vehicle.

Question: What muffler is right for my car?
Answer: This depends on many factors.
  • Do you need an offset muffler?
    This is where your inlet/outlet pipes are located in relation to the muffler.
  • Do you want a stainless steel or aluminized muffler?
    The main difference between the two is the outer shell of the mufflers. Stainless steel mufflers have a polished stainless steel shell and are 100% stainless construction. Stainless steel is better looking and will never rust. Nothing looks better or lasts longer than stainless steel. The aluminized mufflers have stainless internals and necks but have an aluminized outer shell. Also, the aluminized steel has only a protective coating that, if scratched off, may rust. Both mufflers have identical internal construction and materials and both offer you a lifetime warranty and will give you that Straight-through Wide Open Performance with no restrictions. No restrictions equals better flow, and better flow equals more horsepower.
  • Sound of the mufflers?
    The bigger the muffler, the quieter the exhaust.
Question: What sound difference will I get with a smaller muffler as opposed to a larger muffler?
Answer: A smaller muffler is going to give you a much louder sound than you would normally get with a larger muffler. The larger or longer the muffler, the less sound you will get. The smaller or shorter the muffler, the more sound you will get.






Question: What's the difference between Stainless Steel and Aluminized Steel?
Answer: The main difference between the two is pricing and the outer shell of the mufflers. Stainless Steel cost more than Aluminized Steel. The Stainless steel mufflers have a polished stainless steel shell and are 100% stainless construction. Stainless steel is better looking and will never rust. Nothing looks better or lasts longer than stainless steel. The aluminized mufflers have stainless internals and necks but have an aluminized outer shell. Also, the aluminized steel has only a protective coating that, if scratched off, may rust. Both mufflers have identical internal construction and materials and both offer you a lifetime warranty and will give you that Straight-through Wide Open Performance with no restrictions. No restrictions equals better flow, and better flow equals more horsepower.
