I installed the cat-back exhaust along with new factory replacement catalytic converters by Flowmaster. It was an easy install and the quality of the system compared to the factory junk was far superior.. As always AutoAnything has the best deals, and free shipping.

Perfect fit!

Recently replaced the existing cat back Flowmaster exhaust (dual system) with the Force 2 series product ( part #17403- single 3" pipe) on my 2005 Ford F-150. Cant say enough how easy the new system went on after cutting off the old exhaust from the y-pipe behind the cats. Complete instructions (although I didn't really need them) and all the correct parts. Nice mellow exhaust note as well. Very happy with the product!

Great sound, not annoyingly loud

I ordered the Force II system based on the description from Flowmaster and the other user reviews. I wanted a system that would increase performance, sound good, but not drone while cruising and towing. The tone is good, sounds great under hard acceleration, then mellows out really nice.

I purchased the single side system, and was surprised at the ease of installation. The worst part was removing the old exhaust. This is where a sawzall comes in handy.Definatly weld connections. Installed it and didnt weld connections, got on it the first time out and blew exhaust apart, luckily nothing hurt.Sounds excellent at low speeds almost cant hear at cruising speed.The 3" pipe sounds just as good as duel pipes.Boosted mid-range power slightly, cant tell about gas mileage.Also make sure you tack weld stainless tip.Installation took about 2 hours by myself in garage on floor no lift.Dont even mess with stock clamps save time & aggrivation just cut pipe.Very satisfied!!
