    • Get a jak stand or 2nd pair of hands to install it

Easy to install but the flange doesnt line up. And the back hanger I had to bend it up to go in the spot. Otherwise exhaust sounds great and I hope it doesnt leak from the flange part.

Easy to install, put this on my 2011 F150 FX4, superfan with 6.5' bed. Didn't need the extension piece, and only had to cut 2" off the inlet pipe. Great sound, nice deep growl when accelerating, screams when going up hill, but still pretty quiet when at cruising speeds with the windows down. Update (6 weeks after install): The baffle in the muffle broke loose the second day being on the truck and rattled like crazy. Flowmaster was very helpful and easy to deal with, started the warranty right away, took about four to five weeks to get a new muffler. Also, the pipe clamps they give you with the system are garbage. I've had to retighten them multiple times because the muffler will slip off the inlet pipe, even after using a breaker bar to tighten them down. If you want your system to stay together and not fall off your truck going down a highway, welding it together is a must, don't trust the straps to hold it together. Update (1 year 3 months): The second muffler they sent as a replacement to the original started rattling as well, but only at certain RPM, I decided to live with it. But the "stainless steel" is all completely rusted. Replacing shortly with a Stainless Works exhaust. Sounds great, but I wouldn't buy it again. ... show more

Worked great on my 157" wheelbase 2010 f150. Easy install by myself in half hour or less using all original mounting brackets on my truck. No welding, just cut down one extension pipe and everythingbolted securely into place. Looks and sounds excellent.

    • Great exhaust sound for 09-12 F150s
Style: Base Product
Installed on 2010 super cab 5.4 F150, great lower end bass note with minimal cab drone up through the RPM range, measure twice and cut once if you are required to (check instructions) and installation is easy with a lift. If no lift is available a hacksaw or other tool may be required to get the old exhaust off. ... show more
