    • Pretty good Muffler
Color: Center In / Center Out – Round Body
I was after a bit more sound from my 2003 5.3L Tahoe when I purchased the FlowFX. After having this muffler on my truck for several months now I can say it's definitely louder but it wasn't quite the sound I was looking for. There's nothing wrong with it and this is actually a really nice sounding muffler if you're looking for a really smooth sounding exhaust. I would say this is mellower (if that's even a word) then most of the magnaflows I have heard. That being said the flowFX does sound fuller imo then other Flowmaster mufflers out there. Much less tin can sounding and more like a Magnaflow. I personally like my exhaust to have a little more of a throaty sound to it and this was just too bass heavy for me. The biggest down side by far is the presents of drone. After reading some reviews on here, there's a handful of people claiming that the drone isn't bad or is very tolerable but to each their own. I would say this is a solid 6/10 on the drone scale. It's not the worst drone I have heard but it's enough to bother the family on road trips. For this reason I will be removing it from the Tahoe and am going to replace it with something else. I don't fault the muffler for this at all as it's not really claiming to be drone free. The construction of the muffler is good and looks to be high quality. If you don't care about drone and are looking for a smooth and mellow sounding muffler this will do. ... show more

If you are looking for a good growl without obnoxious rasp and on a great budget.... This is the route to go. Sounds very good on a 1uz v8, great growl but not overly loud. Would recommend for sure

Sounds great on my jeep wrangler, pretty loud cold start but calms down after it heats up no codes and its been on there since June of 2025

    • Improved MPG
Color: Center In / Center Out – Round Body
My Jeep JL has been running with the muffler delete kit for 5 years, but I was never really happy with the sound. I had this installed, replacing the factory resonator. This gave the 3.6L JL a mild sound, which I love. However I wasn’t expecting to gain almost 2 MPG with the change.

Color: Center In / Center Out – Round Body
Love this thing, exactly what I wanted my truck to sound like. Deep rumble at start up and acceleration and nice and soft at cruising with no drone.

Good deeper more aggressive sound, not op pound until you want it to be! Fit well on a 2015 ford focus with a 2.0”-2.5” in adapter.

    • For the price?

Honestly for the price you cant beat it. I got two and installed on my camaro ss they were super quiet but then I deleted my resonators and installed an x pipe to pair with these and now she roars

    • Good tone
Color: Center In / Center Out – Round Body
Little too quiet for my taste when I just replaced the muffler with this, but definitely added some real nice tone to my 4.6 F150. Drone was like zero but I like my muffler delete currently. Probably would sound great with a cat delete or headers and pair it with one or two of these.
