This exhaust has a deeper tone than the stock set-up and sounds better than some of the other systems I’ve listened to online, albeit, they may sound different in real-life. The install was quick and easy; it took me longer to cut the original exhaust and remove it than to install this one.

The exhaust sounds great, no drone, nice medium volume level. The only complaint I have is that the pipe doesn’t fit a single cab without cutting it down to the correct length.

I purchased this for my 2022 F150 5.0L Regular Cab w/ Short Wheel Base. It isn’t designed for my truck but after a little cutting I made it work.

Well the flow masterfx for my 2021 f150 5.0 is exactly what I wanted. It is mellow when driving around my apartment But once I get above 2300 rpm the symphony of the v8 is perfect. Driving on highways is ok can still talk without shouting. Do to rpm staying low with the 10 speed trans. This is all with the resonator removed. If I would like it to be quieter, I can reinstall resonator with this kit no issues. I’m in love thank you

Installed on 2010 F150 5.4L I’m going to give it 5stars but the clamps deserve 3stars! Longest part of the project was removing the old exhaust. Package arrived damaged (fedex is the worst) small dent on turndown pipe but you’ll never see it luckily so I went ahead with install. Instructions provided by Flowmaster were detailed and easy to follow. I over engineer things so I added blue loctite to flange bolts. Clamp did not tighten enough to prevent small exhaust leak and liquid drip. I’ll be running a bead of weld tomorrow around junction where extension pipe and muffler pipe join. The Flow FX Extreme is much louder than I anticipated. I watched many videos and they all stated it was pretty quiet. I’m not complaining on the sound, it makes the F150 liven up and sound like a real truck. Matches it’s lifted attitude now!

Easy install with a lift only took about 20-30mins. Nice low tone. Haven’t noticed any drone. Not too loud. Won’t wake the neighbors!

I installed this on my 2024 F150 SCSB 5.0. It took some doing but I installed this while retaining the factory resonator. The sound is deep and growly with little to no cab drone. No raspy or cracking sound. Just the sound I was looking for. I love the look (or lack thereof) as well. It is tucked out of sight which I prefer. I want to hear it, not see it. Can’t beat the price either IMO

Easy and light to install removing stock exhaust is a pain but easy if cut into smaller sections.
