    Bought this item and put it on my truck and it sounds great. Price and delivery time was perfect! I’m glad I found this website that has affordable upgrades for my 2010 F-150

    Love the sound and that’s about it! My truck is super crew with 6.5′ bed and needed the extension tube needed trimmed. The description said it would fit, which it did but needed modifications. First, the extension pipe wouldn’t slide into the muffler without being bent and then hammered in. Next, after being bolted to the cat. converter and the muffler hung WITH the extension pipe it wouldn’t slide together. Had to trim the pipe that was bolted to the cat. A couple modifications, parts not fitting together, and taking a 1 hour project into a 4 hour made this a 3 star. The shipping, sound of the exhaust, ease of buying, and not having to move the hangers carry this product.

    It was pretty straightforward. Had to move the middle mount and re drill a tap to frame. Looks good and sounds good.

    Easy install sounds great deep rumble A little loud on the highway you will need to turn the radio up

  5. GayTruck –

    Super easy install. No need to jack track up. Plenty of clearance. Sounds great. Nice deep roar WITHOUT annoying drone while highway cruising. Great product.

  6. NickBNH –

    This is a great system can’t beat the price it took longer to remove the old system than it took to install the new system it took about 30 minutes to install the newer system in my driveway once I removed the old

  7. CroweEcoBoost –

    Product is worth the money very easy install and the truck definitely sounds more aggressive but not overly annoying

  8. Fzcodie –

    Exactly what I wanted quiet at idle and loud when you want it, also not annoying on highway glad I went with this

    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!

  10. TULLER –

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