Product Details

The Roush Performance 421248 is a complete cat-back exhaust system engineered to enhance power, fuel efficiency, and sound for 2005-2008 Ford F-150 trucks. This "Legal" exhaust system delivers a deeper, more aggressive exhaust note while maintaining sound levels within legal limits for production vehicles.

Key Features:

  • Mandrel-bent tubing maintains consistent internal diameter throughout all bends, maximizing exhaust flow and unlocking hidden horsepower and torque
  • T-304 stainless steel construction provides superior corrosion and stain resistance for long-lasting durability
  • Dual rear exit design with under-bumper tips for an aggressive appearance
  • 50-state legal sound levels meet production vehicle noise requirements
  • Complete bolt-on kit designed for straightforward installation

Compatibility: This exhaust system is specifically designed for 2005-2008 Ford F-150 4x2 and 4x4 models equipped with 4.6L or 5.4L V8 engines. Fits SuperCab with 6.5-foot bed and SuperCrew Cab with 5.5-foot bed configurations.

The mandrel-bent design delivers significantly improved exhaust flow compared to factory crush-bent pipes, resulting in measurable gains in both performance and fuel economy. The premium stainless steel construction ensures this system will outlast the factory exhaust while providing years of reliable service.

had the parts required at a competitive price with free shipping, whats not to like.. ;)

I request no offers via e-mail or phone and would like my info to not be shared

Fine

As I'm concerned that this item will work with my stock 65 El Camino, your site came up when looking for the specifics and since I really don't know what it looks like, can only hope it will work (hence, my giving 4 stars).

Good service. Item doesn't fit, wrong size. Awaiting RMA to return for refund.

Site was easy and price was reasonable.

Excelent

Please send the one exactly as pictured on the website. Thanks

I would def order again from them great price and fast shipping.

Autoplicity best price on the web,FAST delivery, ordered wed. afternoon and received friday. AAAA++ RATING Will be ording from in the near future.

SO far, so good. We ordered a new Weathertech Trunk Liner from Autoplicity for our new VW SportWagen. We were pleased to find exactly what we were looking for for $50 less than other locations.
