Great muffler.
Sounds great fits great. Nice deep rumble. Very quiet at cruising speeds. Very little drone in the cab. Pretty quiet muffler overall. I would highly recommend.

Pretty good Muffler
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.

Good for day to day use
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.

So much better than a glass pack. Do it!!!
Why did you pick this product vs others?: Love it. Its like a better glass pack. Almost quieter than stock at idle. Loud and raspy at full throttle. Cruising at 80mph its nice and mellow. Pass someone and it sounds like you mean business. And this is side piped ahead of the rear wheel.

Back in the old days, I used to pay a fortune for these branded mufflers to be shipped from the States to Dubai. Thanks to Amazon, I can now buy quality stainless steel Flowmaster mufflers for the same price I'd pay if I was in the States, and same day delivery! Big thumbs up! 2.5" is the size of the inlet/outlet pipes internal diameter, by the way.

I don’t like that it came in a very beat up and old looking box, but the muffler was fine. Just some minor scratches but nothing that affects the mufflers use or performance.
