One Complete Package. Ready to upgrade your exhaust but don't want to spend a long time mixing and matching individual parts? Grab this powerful Y-pipe set that comes complete with headers and catalytic converters to get your overhaul done faster. The split design merges with a mitered seam to create proper mixing of the reunited flows, while the tubing is the maximum 3 in. diameter for the fastest flow speed possible.

Tough for Rough Roads. Flying rocks, road salt, and scouring sands won't leave you with exhaust leaks when you put in this tough Y-pipe set. The tubing is mandrel-formed from 16-gauge stainless steel. The chromium content prevents corrosion from the usual suspects while the thickness of the metal stops dings and dents in their tracks.

Catalytic Conversion. The stock converters on Ford F-150s are notorious for throttling the power of the engine, especially on the 5.4L model. Unleash your truck's true potential while remaining within the emissions limits set by 48 states with this powerful exhaust upgrade.

Quick Installation. Exhaust improvements always take a few hours, but the ball sockets and snap-on attachment points for this Y-pipe greatly simplify the process. You won't need to drill into your frame or suspension because the attachment points on this part line up with the factory openings.

Application. This aftermarket part works with 5.4L Ford F-150s made from 2004 to 2008.
