Flowmaster
Flowmaster 40 Series Delta Flow Mufflers

Product images may differ from actual product appearance.

The two-chamber design of these mufflers incorporates Flowmaster's patented Delta Flow technology. Delta deflectors result in increased scavenging for better performance and reduced interior resonance over standard 40 Series Mufflers.

Features
  • For 4-cylinder and 6-cylinder applications with limited space
  • The quietest muffler of the dual chamber 40 Series plus reduced interior resonance
  • Case: 13" L (4" Thick)
  • Overall: 19" L x 9.75" W
  • Aluminized steel or 409S stainless steel (stainless has limited lifetime warranty)
  • MIG welded for maximum durability
