Flowmaster 817696 Outlaw Cat-back Exhaust System

It has a great sound. Sometimes I wish it was louder, other times I wish it were quieter. All in all, I’d buy it again. Installation was easy, I did have to cut the pipe a little bit, and unfortunately one of the clamps on the exhaust tips broke while tightening, so that was disappointing. But I ended up using aftermarket heavy duty clamps until I can find the time to weld the tips on. It looks great, it sounds decent (better than stock anyway). Not too loud, but you can definitely hear the droning inside the cab.

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.

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".

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.

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.
