About this item

  • No internal packing to blowout
  • Excellent Street/Strip and Off Road application
  • Race proven Delta Flow technology
  • Durable fully welded 16 gauge aluminized steel


This two chamber design incorporates Flowmaster's Delta Flow technology. The Delta deflectors generate increased scavenging for better performance and reduced interior sound. Milder exterior tone and reduced interior resonance over Original 40 series. Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.

Great sounding muffler. Some drone at highway speeds but not overpowering. I would buy it again!
