Product Details

The Flowmaster 40 Series Delta Flow Chambered Muffler delivers an aggressive, deep tone for enthusiasts seeking maximum performance sound. Engineered with Flowmaster's race-proven Delta Flow technology, this muffler uses a chambered design that creates backpressure to enhance exhaust scavenging while producing the distinctive Flowmaster sound.

Key Features:

  • Delta Flow technology with chambered construction for aggressive exhaust note
  • No internal packing materials that can deteriorate or blow out over time
  • Fully welded 409 stainless steel construction for durability and corrosion resistance
  • Ideal for street/strip performance vehicles and off-road applications
  • Moderate interior sound level with aggressive exterior tone

This muffler is designed for performance enthusiasts who want a deep, aggressive sound without sacrificing reliability. The welded stainless steel construction ensures long-lasting performance in demanding conditions, while the packingless design means consistent sound and flow characteristics throughout the life of the muffler.

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

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

Great website, this makes car part buying real easy!

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.

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!!
