The Flowmaster Force II Cat-Back Exhaust System is engineered for 2004-2008 Ford F-150 and Lincoln Mark LT trucks equipped with the 4.6L or 5.4L engine. This system is the ideal choice for drivers seeking a subtle custom appearance combined with the proven performance and sound benefits of a Flowmaster single cat-back exhaust system.

Designed to deliver a moderate exterior exhaust tone with a mild to moderate interior sound level, the Force II system improves efficiency without introducing excessive noise. This bolt-on exhaust system increases tubing size to 3.00-inch mandrel-bent stainless steel tubing, flowing into a Super 50 Series chambered muffler for improved sound control and performance over the factory exhaust.

The mandrel-bent tailpipe connects after the factory catalytic converter and uses the factory hanger locations for a precise fit and straightforward installation. The system is finished with a 3.50-inch polished stainless steel exhaust tip for a clean, refined appearance. Ideal for daily driving and light towing applications such as boats and RVs, this exhaust system includes all necessary parts and hardware for at-home installation. Stainless steel systems are covered by Flowmaster’s Lifetime Limited Warranty.

Note: This Force II system is also available in aluminized steel with a 3-year Limited Warranty.
