Product Details

The Flowmaster 52573 70 Series Chambered Muffler delivers a mild exhaust tone with minimal interior resonance, making it an ideal choice for daily drivers who want improved performance without excessive noise. This chambered muffler design enhances horsepower, torque, and overall engine efficiency while maintaining a near-stock sound level on the exterior.

Key Features:

  • 70 Series chambered design for balanced sound control
  • Minimal interior drone and resonance for comfortable highway driving
  • Mild to stock exterior exhaust tone—perfect for noise-sensitive areas
  • Increases horsepower and torque across the RPM range
  • Improves engine efficiency and throttle response
  • Specifically recommended for SUVs, trucks, motorhomes, and tow vehicles
  • Durable aluminized steel construction for long-lasting performance

Engineered for larger vehicles and work trucks, the 70 Series is Flowmaster's quietest chambered muffler, providing the performance benefits of a free-flowing exhaust system without the aggressive sound. This makes it an excellent upgrade for anyone who needs towing power and improved fuel efficiency while maintaining a refined exhaust note.

Fast service and shipping, Plus the lowest price for the high performance k&n air filter<br>I wanted.

Easy website!

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

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.

Thanks for you swift respond for the email and your accurate information and i hope to deal with you again

Completely amazed by this seller. I recieved the rack in just 2 days and the price was unbeatable. I'm just stoked to have finally found a bike rack worth having!!
