    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)
