Description
Overview
The Flowmaster 60 Series Delta Flow Chambered Muffler is engineered specifically for smaller displacement 4 and 6 cylinder engines, delivering a mellow, refined tone alongside real gains in power and throttle response. Built around Flowmaster’s proven Delta Flow® technology, this muffler channels exhaust gases through a precisely designed chambered path that improves flow while keeping the overall sound level moderate — ideal for drivers who want a noticeable upgrade without an overpowering drone.
Constructed from 16 gauge aluminized steel and fully MIG welded, the 60 Series is designed to stand up to the heat, vibration, and demands of everyday driving. A high-temperature paint finish adds another layer of protection to help the muffler endure the harsh underbody environment mile after mile.
Key Benefits
Delta Flow® technology is the heart of the 60 Series, using strategically placed internal chambers to smooth exhaust pulses and produce a clean, mellow exhaust note. On 4 and 6 cylinder vehicles, that translates to improved power and sharper throttle response while maintaining a comfortable, moderate sound level that stays civilized on the highway and around town.

Sound & Configuration
The 60 Series produces a mellow tone that pairs well with the character of smaller displacement engines. Because tailpipe and tip diameter directly influence the final note, choosing a larger diameter tailpipe or tip will create a deeper tone that’s evident both inside and outside the vehicle — giving you the ability to fine-tune the sound to your taste. Exhaust tips are sold separately, so you can match the outlet hardware to the look and tone you’re after.
Fitment & Installation
This is a universal muffler with a 2.25″ inlet diameter, making it a versatile option for a wide range of 4 and 6 cylinder applications. It is generally suited to rear mount installations and uses new hangers, which are not included, allowing you to set up the mounting to fit your specific build. The muffler carries an emission code of 5. Always confirm inlet size and mounting requirements against your vehicle’s exhaust system before ordering to ensure a proper fit.
For enthusiasts who want a balanced blend of durability, refined sound, and real performance gains on their four- or six-cylinder vehicle, the Flowmaster 60 Series Delta Flow Chambered Muffler delivers a proven, well-built solution.
