Flowmaster 50 Series Delta Flow Three Chamber Muffler

Product List Loading:  wait
Flowmaster's 50 Series H.D. muffler is designed for modern, higher horsepower trucks. This muffler is ideal when a deeper, more aggressive tone is desired. This muffler features a 4.00-inch internal design, designed for trucks with modified engines. It is built from 16 gauge aluminized steel and comes in various inlet/outlet configurations. Flowmasters 50 Series SUV Performance Delta Flow muffler is specially designed for trucks, light SUVs and high horsepower vehicles. The larger H-chamber reduces interior resonance, crucial in longer vehicles like trucks and SUVs. Constructed of 16 gauge aluminized steel and fully mig-welded for maximum durability. Developed from Flowmaster's line of Delta Force race mufflers, Delta Flow technology provides superior scavenging of exhaust gases even over a comparable (standard) Flowmaster muffler. By using multiple deflectors vs. a single deflector, Delta Flow technology provides a cleaner and faster scavenging path by eliminating the chance of turbulence commonly found behind a single deflector model. These Delta Flow deflectors can only function properly when they've been precisely placed and welded to exact specifications.
Developed from Flowmaster's Delta Force race mufflers. Flowmaster mufflers with Delta Flow technology provide superior scavenging of exhaust gases than a comparable (standard) Flowmaster muffler. The results: increased horsepower, torque and fuel economy along with reductions in exterior sound levels and interior resonances.

Product Reviews
5 out of 5 stars 92 F150
Review for: 50 Series Delta-Flow Performance Street
From Charlotte, NC Reviewer: Michael Cahill   Own this product - Yes
It was a tight fit for my truck, has a good sound, very mellow inside the cab, but sounds good outside the truck. The only thing I would complain about for the product is that getting pipe clamps to hold it, you have to use the cheap ones. The higher end ones that clamp around the pipe 2 wide dont hold tight enough.
5 out of 5 stars great sound
Review for: 50 Delta Flow Muffler - 2.50 Offset In / 2.50 Center Out - Moderate Sound
From Tennessee Reviewer: Dustin Ivey   Own this product - Yes
These are great, i put them on a 1970 chevy chevelle and they sound great on the outside its good and deep and on a scale of 1-to-5 i give it a 4. As for the sound in the car it is very small i rate it a 1 on a scale between 1-to-5. highly recomend.

I found the fasttrackautoparts.com website to be easy to use and prices very competitive. For my particular order there was a three day delay because the item was not in stock, but I was notified by email and received delivery within 12 days of order.
