Race Car Roar. Tear up the road with the Force II Stainless Steel Cat-Back Exhaust System by Flowmaster. This inclusive kit includes all the necessary mandrel bent tubing to increase the noise your truck makes when it’s rumbling down the road. Make a statement well before your entrance with the deep, throaty tones of this system.

Power in the Performance. This Cat-Back Exhaust System comes equipped with the Super 50 Series Muffler, which combines with the tubing to complete the beastly sound. After installation, this kit removes many of the previous restrictions of the stock exhaust, giving you higher torque and better horsepower.

Quality Construction. All Flowmaster products are proudly constructed in the United States, so you know the Force II Cat-Back Exhaust will be high quality. The 3 inch inlet/dual 2.5 inch outlet tubing is created with 409 stainless steel, with a 16 gauge design. The system was built to be corrosion resistant, and the tips are decorated with the “Flowmaster” logo to add a touch of style.

Easy Installation.This kit was designed to easily replace the stock exhaust on the truck, which means it installs using existing equipment on the truck. You’ll need a set of basic hand tools, and you won’t have to use any modifications. You’ll get that satisfying rumble after an afternoon of adjustments.

Application.This Flowmaster Force II Stainless Steel Cat-Back Exhaust is designed to fit on all 2009 to 2010 F-150s powered by the 5.4L engine. It is not compatible with the 5.4L SVT Raptor.

Is the Force II, Series 50, drone substantially less pronounced than the American Thunder, Super 40, and is it day to day live able? I have the American Thunder on my 2014 GT and the drone was too much for me. I don't want my neighbors to hate me. Thanks.

  • Hey Ken, So the Force II are going to be noticeably less loud than the American Thunder. Of course I cannot give an exact level but they are designed to be just a slight upgrade from stock. Flow master, in terms quietest to loudest, goes Force II -> American Thunder -> Outlaw. So there will be a decrease in sound so that your neighbors will not hate you.

I don't see a place to input bed size, I have a 5.7 bed. will this system work?

  • This system will work with a short bed or long bed as this comes with extension pipes that you can put on your truck if you need to have them on there.
