I received the wrong size was for a 5.5/6.5 bed not my 8 ft bed. Had to bring it to a shop to have them custom fit it mo- money. The sound is loud at start and take off but smooths out and notices it have lees resistance from the gass peddle especially on the highway. Little loud but sounds good. Biggest disappointment is the delivery service fed-ex never on schedule they make and had to chech every piece after watching them repac my exhaust in my driveway since it was scattere on the floor.

Very happy with thr outlaw system from flowmaster. Had it installed at a local muffler shop and had them weld it up to insure no exhaust leaks. Sounds killer and would recommend it to anyone looking for a good exhaust system. Its not too loud in the cab either like I thought it would be. Its perfect!

I'm pretty happy with it. You can find cheaper products, but this looks and sounds pretty good. I think it was worth the extra. My only complaint was the installation. The old came off easy, the new parts went on great. The spring clamps are junk. I couldn't get most of them tightened down enough to hold the pipes together. Ended up breaking off bolts on 4 of them. Eventually bought some standard muffler clamps and everything tightened up like it should.

this is exactly what i was looking for. it was easy to install. great value and it sounds just like i had hoped. it gives my truck that "animal growl" when i get into it. i would recommend this exhaust to anyone looking to up the performance of their vehicle.

The Flowmaster Outlaw system definitely did not disappoint! Sounds amazing and makes me want to drive around just to listen to it! The only problem with installation was if you decided to go dual out the back the pipes were too long and it jutted out way too far. But some simple measuring and cutting of the pipes had that problem solved very quickly.
