    The muffler that started it all: Flowmaster's 40 Series. Made of aluminized or stainless steel, these are the most aggressive sounding street/strip mufflers in the Flowmaster lineup. They also create resonance in the vehicle so, if you want "surround sound" from your exhaust, look no further.


    Features
  • For street and strip applications
  • Loud, aggressive sound with 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)
  • Stainless mufflers are painted dark grey metallic to improve resistance from the elements
  • MIG welded for maximum durability

  • Does this fit your vehicle?

    Rated 5 out of 5 by from Great set of mufflers! The quality and sound are great, just as loud as I'd hoped they would be. They are loud and do cause interior resonance especially in an older Vette where the cabin is so tight but I love the way they sound. And as always a great experience from Jegs.
