Flowmaster 817696 Outlaw Cat-back Exhaust System

Installed on 2005 f150 5.4 v-8 crew cab 4x4 truck. The sound is super, and I was surprised with how little drone in the cab. Only loud when on the throttle hard. Very nice quality and installed easy with no problems in 3 hrs.

Good instructions and installed really easy. Makes the truck sound really good.

If you are looking for a LOUD exhaust, this is what you want. I love it, it makes the truck sound like an 8 cylinder should. Installation was good, only a couple things had to be tweaked. It takes an "average truck" and makes it "not so average".

Dont fit in a 2004 f150 fx4, the peices make the pipe go straight into a support piece in the frame and is impossible to put in the truck unless i make my own things cause what is supplied doesnt work

Overall good product, One pipes were installed in the correct place I was short by about 2 inches from the muffler to the pipe that goes under the passenger side door. I had to get an extension from my local auto part store to fix that issue. After I fixed that and everything was installed it was impossible to get the muffler tips on. They are almost the exact same size as the 3 in muffler pipes. I had to order an adapter so that I can install the muffler tips and make them level with each other. Good product overall, but they need to fix a couple of their products.

Great set up! Easy to install.Price was fair. Bought it threw Amazon and saved about $150 dollars.Everything fit perfectly would recommend it to others. This is the second one I have purchased. Bought the first one for my daughters 2007 Ford F150 5.4 Triton and liked it so much I bought one for my 2019 Chevrolet Silverado 5.3. Install took about 3-4 hours.

let me tell yall this thing is monster ready to be unleashed under my truck. there's no tingy sound no poppy sound when you take off. it just has that deep sexy tone to it. i put it on my 2008 f150 supercab 4x4 6,5 bed 4.6. fits in there wonderfully. had to do some twists and tursn in there to get it just right but it fit. the only thing is i didnt get my flowmaster sticker :((((

Quality product. Had it installed professionally. Tach welded all joints. Sounds very aggressive and throaty. Saved about $250 buying it on Amazon then having it installed. Definetly will recommend.
