2004-2008 F150 5.4L Stainless Works S-Tube Factory Connect Dual Rear Cat-Back Kit 08F150TDYUB

Brutal New Exhaust Note with Improved Performance and Quality

Nobody does high-quality cat-back exhaust systems like our friends over at Stainless Works, and this kit comes standard with a pair of extremely powerful S-Tube performance mufflers that are built from the ground up to deliver a deep, throaty, and wholly aggressive sound to that 5.4L Triton V8 under the hood of your 2004 to 2008 F150. Each of these complete F150 cat-back exhaust kits bolts on in place of your stock cat-back system and features a dual rear exit configuration to change up the look of your tough F150 truck while getting it the awesome sound and extra performance that it needs to really shine on the street or the trail. The Stainless Works S-Tube cat-back kit gives your truck a ferocious new sound with top-notch quality and fitment.

High-Quality 304 Stainless Steel with Performance Mufflers

The Stainless Works S-Tube Dual Rear Exit Cat-Back System is built using only the best materials and is much more efficient than your factory cat-back kit. Stainless Works manufactures each one of these kits using 2.5" diameter tubing that's all mandrel-bent to provide smooth exhaust pathways with minimal back pressure and restrictions. The kit is fitted with Stainless Works' S-Tube mufflers which feature a specialized straight-through design that generates a loud, deep tone while keeping drone at cruising and idle fairly low. Every kit finishes up in a pair of 3.5" polished exhaust tips that exit out the rear of your truck under its bumper. The kit is made entirely out of high-quality 304L stainless steel which can resist corrosion and discoloration in practically any climate. Each kit comes with a full set of clamps, hangars, hardware and instructions.

F150 Fitment: this cat-back kit will only fit trucks with a SuperCrew cab with a 5.5ft or 6.5ft bed and SuperCabs with a 6.5ft bed. The kit features a Stainless Works Factory Connect inlet pipe assembly and will not fit Stainless Works Performance Connect long tube headers and mid-pipes.
