Speed Engineering 2015–2023 Ford Mustang 1-7/8" Longtube Headers & X-Pipe Full Kit (5.0L Coyote) 25-1085
$769.96
Speed Engineering 1-7/8" Longtube Headers & X-Pipe Full Kit for 2015–2023 Ford Mustang 5.0L Coyote applications.
This complete bolt-on system replaces the restrictive factory exhaust manifolds and mid-pipes with free-flowing stainless longtubes and a 3" off-road X-pipe that connects directly to the existing axle-back location. Designed for significant horsepower gains, aggressive exhaust tone, and long-lasting durability.
⚠️ Note: Rear (downstream) O₂ sensors are not used. A check-engine light for catalyst efficiency will appear and must be disabled via PCM tuning.
Kit Includes
- (1) Pair of stainless steel 1-7/8" Longtube Headers
- (1) 3" Off-Road X-Pipe / Connection Pipe
- (2) MLS Exhaust Gaskets
- (2) O₂ Extension Harnesses
Plug Wires and Sleeves can be added to the kit if selected.
Speed Engineering Mustang Coyote longtube headers are made out of 304 stainless steel and offer great quality, performance, and affordability. Our Mustang Coyote longtube headers are mandrel bent, tig welded, and feature natural stainless steel construction. All of our Mustang Coyote longtube headers have been dyno proven. We stand behind our Mustang Coyote longtube headers in saying you will not find a better fitting, quality built, budget header for your vehicle.
You will need o2 extensions as the upstream o2 bungs will be located further back with these headers. The rear downstream o2 sensors will no longer be used

Fit perfect
For me the ball joints came bolted in on both upper control arm.
The also make it easier for future bushings replacements, by not being pressed fit. They also have grease ports to grease the bushings.
