SLP 1-3/4-Inch Long Tube Headers and Catted Shorty X-pipe; Ceramic (11-14 GT)
Dyno-proven Rear Wheel Gains. Get the most power out of your 5.0 coyote with a SLP Long Tube Header and catted X-Pipe combo kit. These SLP ceramic coated headers replace your restrictive factory manifolds to improve exhaust flow and increase your Pony's horsepower and torque. Increases of up to 28 RWHP and 27 RWTQ have been seen when installed with the included SLP shorty X-Pipe.

Aluminum Ceramic Coating. SLP uses a durable Aluminum Ceramic Coating (inside and out) on its long tube headers to reduce under hood temperatures, increase horsepower, lengthen the headers life, and for it's outstanding good looks. Ceramic Coated headers will long out last both polished and chrome plated headers.

Made In The USA. Hand-crafted right here in the U.S.A from 1-3/4" CNC mandrel bent stainless steel tubing, these SLP Long Tube Mustang Exhaust headers have a 4-into-1 design that merge into 3" collectors. The collectors feature an integrated venturi-style spike to optimize exhaust flow, resulting in a monster increase of horsepower.

High Flow Cats. The included SLP Mid Pipe uses CNC mandrel-bent 3" stainless steel tubing with a genuine X style crossover for a raspy race car sound and features a pair of 3" 200 cell per inch high-flow catalytic converters to provide a significant horsepower increase over the restrictive factory catted pipes.

Recommended Upgrade. To realize the full power potential that this Header and X-Pipe combo kit has to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. This SLP long tube header and matching catted X-Pipe combo kit is specifically designed for the 2011 to 2014 GT Mustangs equipped with the 4-valve 5.0L coyote engine. Compatible with factory or SLP Axle-Back Exhaust Systems.
