2011-2014 Mustang GT 5.0L BBK 3" Shorty Catted X-Pipe 1658

BBK Shorty Catted X-Pipe Racing Exhaust w/ Converters

If you're looking to get the most out of your Mustang by gaining a raspy race car growl and a big increase of horsepower for competing at the track, look no further than Industry-Leader BBK's Shorty Catted X-Pipe. This Aluminized X-Pipe out-performs the restrictive stock factory catted H-Pipe by producing more horsepower and torque at the rear wheels. Designed with a modern "X" crossover pipe design, the X-shaped piping was designed specifically to work perfectly with your 5.0L engine. The welded, mandrel-bent tubing allows for substantially better airflow over stock and is guaranteed to provide long-lasting performance and zero sound degradation over time.

Durable BBK Quality X-Pipe

BBK's X-Pipes use a free-flowing 3" diameter CNC mandrel bent Aluminized Tubing and a merged X crossover to improve flow. The High-Flow catalytic converters were Dyno-Tested by BBK and show a significant horsepower increase over the restrictive stock cats.

Dyno-Results: +15-20 Horsepower Increase
