Product Details

The Flowmaster 40 Series Delta Flow Chambered Muffler delivers an aggressive exhaust tone with proven performance technology. Engineered with Flowmaster's proprietary Delta Flow design, this muffler uses strategically positioned internal chambers to reduce backpressure while producing the signature deep, powerful sound that enthusiasts demand.

Key Features:

  • Delta Flow technology maximizes exhaust flow and power output
  • No internal packing materials that can deteriorate or blow out over time
  • Fully welded 16-gauge aluminized steel construction for long-lasting durability
  • Race-proven design suitable for street, strip, and off-road applications
  • Moderate to aggressive exterior sound level with deep tone
  • Direct replacement chambered muffler design

This 40 Series muffler is ideal for drivers seeking performance gains and an authoritative exhaust note without sacrificing quality or reliability. The all-steel welded construction ensures leak-free operation, while the chambered design provides excellent flow characteristics for improved horsepower and torque. Perfect for trucks, muscle cars, and performance vehicles where sound and performance matter.

Simple and easy.....Thanks!

Tami Brownlee is Awesome!! I will be back to oder more parts for my race car soon as well as my daily driven vehicles.

Easy to navigate Processing and shipping seemed to take awhile

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.

Quick Fast Low pricing thanks….
