Mild Flowmaster Sound. Are you looking to improve the power, performance and sound of your tenth generation 4.6L V8 powered F-150? If so, then look no further than a Force II Cat-Back Exhaust from Flowmaster. This Cat-Back Exhaust System was dyno-tuned and engineered with ultra-smooth mandrel-bent tubing to improve your F-150's exhaust flow for maximum performance. Not only will this system improve your F-150's performance, but it will also improve your truck's exhaust note as well. Featuring Flowmaster's Super 50 Series Muffler, it delivers a mild to moderate tone that won't drown out your tunes or be to obnoxious when under load.

Quality Construction. Flowmaster proudly manufactures their Exhaust Systems right here in the USA. This Flowmaster Force II Cat-Back Exhaust is constructed from 2.5" mandrel bent aluminized steel tubing for strength and corrosion resistance. This Cat-Back includes a Super 50 Series Muffler that features a single inlet and dual outlet  that connects to a pair of mirror polished 3" exhaust tips. As an added bonus, the tips are embossed with the Flowmaster logo for true custom styling.

Bolt-On Installation. Flowmaster engineered this kit to be a direct fit upgrade replacement for your F-150 stock exhaust. All of the necessary hardware is included and installs easily with just basic hand tools. Depending on model year, some minor cutting may be required. The exhaust tips can be positioned to exit at the rear of your truck or behind each rear tire for impressive looks - the choice is up to you.

Application. This Flowmaster 2.5" Force II Aluminized Steel Cat-Back Exhaust System is designed to fit all 1998 to 2003 F-150s powered by the 4.6L V8 engine. Does not fit the 1997 model year.

How difficult is this to install? Does it require the use of a welder? Does it connect right on the stock cats? Is there any modifying needed to fit this to my truck?

I have an 03 Heritage edition (only 16k made), This product does not work on Harley Edition and I don't know if the Heritage edition is built on the standard edition or the Harley edition platform Will it work?

    Sounds great! Very timid with deep rumble when at idle and daily driving but really screams when you stomp the pedal. Especially when paired with shorty headers and if you you really want to open up the exhaust then cut the cats!
