Flowmaster Force II Catback Exhaust (04-08 F150)

Fitment. Whether cruising on the highway or towing heavy loads, get the power you want for your 04-08 F150's 4.6L or 5.4L without window-shaking, neighbor-waking noise. This Force II series exhaust fits all cab and bed length combos to deliver exceptional performance and looks without an overly aggressive exhaust note.

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 Single Rear Design. A catback design means this system is street-legal.* And if you want an understated custom look, this system definitely delivers - the single out side (SOS) design of this exhaust exits the rear of the truck at an angle towards the corner for a subtle sporty touch.

Quality Construction. The 3" 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 massive 3.5" polished stainless, logo embossed tip gives 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.
