Flowmaster Force II Dual Catback Exhaust (04-08 F150)

Fitment. Enjoy the performance you want without the noise you don't - your 04-08 4.6L or 5.4L F150 can now have the Flowmaster advantage without an overly aggressive exhaust tone. Fits all cab and bed length combos with only minor modifications required.*

Big Gains. The Force II series gives you all the performance you've come to expect from Flowmaster without a huge increase in exterior and interior volume. You'll enjoy an average of 5-10% more power for greater acceleration and passing power. But don't worry - unlike the American Thunder series, this system won't drown out the sound of your awesome sound system at cruise.

Perfect for Towing. Keep everything quiet on the home front when you're towing with this system. It's the perfect choice for the power gains and for the fact that you won't blow the windows out of your RV.

Catback Dual Exit Design. A catback design means this system is street-legal.** And just so you can choose the unique look of your system, Flowmaster includes two different pairs of pipes to configure the dual rear exit so that your tips are angled towards the corners or in a traditional straight-back alignment.

Quality Construction. The 2.5" aluminized steel pipe used to make this rugged system is mandrel-bent for free-flowing, high-revving performance. Complete with Flowmaster's famous 50 Series Performance chambered muffler, this system is backed by Flowmaster's 3 year warranty so you don't have to worry once installing it on your truck. And as if that weren't enough, the 3" polished stainless, logo embossed tips give this system the trademark appearance Flowmaster is known for.

Easy Installation. When choosing an exhaust, you want a simple, straightforward installation. The Flowmaster Force II series contains all the parts you need, including band clamps and hardware, for a simple installation with a minimum of cutting.
