Product Details

The Flowmaster 40 Series Chambered Muffler delivers an aggressive exhaust tone that's perfect for enthusiasts seeking a bold sound with proven performance. This muffler features Flowmaster's original two-chamber design that produces a deep, powerful exterior exhaust note while maintaining moderate interior resonance.

Key Features:

  • Aggressive exterior exhaust tone with noticeable interior resonance
  • Two-chamber design for enhanced exhaust flow and performance
  • Fully welded 16-gauge aluminized steel construction for maximum durability
  • Ideal for street/strip, off-road, and performance applications
  • No internal packing or baffles to degrade or blow out over time
  • Direct bolt-on installation for easy fitment

The 40 Series is Flowmaster's most popular muffler line, trusted by performance enthusiasts for decades. Its chambered design uses precisely engineered internal chambers to cancel specific sound frequencies while allowing exhaust gases to flow efficiently. The result is improved horsepower and torque combined with that unmistakable Flowmaster sound. Built to withstand extreme temperatures and harsh conditions, this muffler is backed by Flowmaster's commitment to quality and performance.

California Proposition 65

very fast processing received product within a few days. fair prices. will do business with again.

The part I needed at a good price, shipped promptly. What is there not to like!

I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.

Easy!
