2-3/4 X-Pipe w/Cats 05-10 Mustang GT 4.6L

The 2-3/4 X-Pipe with Cats for 2005–2010 Mustang GT 4.6L by BBK Performance is designed for automotive enthusiasts looking to enhance exhaust flow and mid-range torque while remaining emissions compliant. This crossover pipe effectively replaces the factory restriction and balances exhaust pulse between both cylinder banks, making it an essential upgrade for naturally aspirated 4.6L builds.

Constructed from mandrel-bent 2-3/4-inch diameter tubing, the X-pipe minimizes turbulence and backpressure compared to factory H-pipe designs. The integrated high-flow catalytic converters ensure OBD-II compliance while reducing restriction, which is vital for achieving dyno gains in the 3000–6000 RPM range where most street driving occurs.

This upgrade is perfect for 2005–2010 Mustang GT owners who are running naturally aspirated or moderately boosted applications and desire tangible improvements in drivability without the need for full resonator removal. Installation is straightforward, requiring only jack support and basic exhaust work—no welding is necessary for a seamless fit.
