BBK 16413 1-5/8 Long Tube Headers & Catted X-Pipe Silver Ceramic 05-10 Mustang

Vehicle Fitment

• 2005-2010 Ford Mustang GT (4.6L V8, Manual and Automatic Transmission)

Fitment Notes

• Designed to replace the factory shorty-style headers and factory mid-pipe - bolts directly to any factory-style cat-back exhaust system.
• Requires 2 sets of O2 wire harness extensions for proper installation - sold separately (BBK Part #1676).
• Not CARB approved - intended for off-road and race use only. Not legal for use on emission-controlled vehicles in California or states adopting California emission standards.
• BBK recommends pairing with a BBK shorty X-pipe for maximum performance gains.

Features

• Full-length 1-5/8" primary tube design creates unrestricted, balanced exhaust flow for gains of 14-22 RWHP when paired with a BBK shorty X-pipe.
• CNC mandrel-bent tubing maintains a consistent diameter throughout for maximum unrestricted flow.
• 3/8" thick laser-cut exhaust flanges provide added strength and a leak-free, OEM-quality seal.
• Patented scavenging collector design maximizes exhaust velocity and cross-cylinder scavenging for peak horsepower across the RPM range.
• Gasket-less ball and socket connectors make mid-pipe connection simple and seal tight without gaskets.
• High-flow catalytic converters on the included X-pipe provide meaningful power gains while retaining emissions hardware.
• Polished silver ceramic coating reduces underhood temperatures, extends header life, and retains heat in the exhaust for improved flow efficiency.
• Pressure tested for leak-free performance - designed and manufactured in the USA.

Product Description

The BBK 16413 is a complete long tube header and catted X-pipe kit engineered specifically for the 2005-2010 Ford Mustang GT with the 4.6L V8. This system replaces the factory shorty manifolds and mid-pipe with full-length 1-5/8" CNC mandrel-bent headers finished in BBK's polished silver ceramic coating, paired with a high-flow catted shorty X-pipe. The result is a dramatic improvement in exhaust scavenging, cross-cylinder flow, and overall exhaust velocity - delivering dyno-proven gains of 14-22 RWHP and a significantly more aggressive exhaust note.

BBK engineered this kit as a true bolt-on system that connects directly to any factory-style cat-back exhaust, making installation straightforward for experienced DIYers. The 3/8" laser-cut flanges ensure a tight, leak-free seal at the cylinder head, while the patented ball and socket collector connections simplify mid-pipe hookup without gaskets. The silver ceramic coating not only looks great in the engine bay but also manages underhood heat effectively and extends the service life of the headers far beyond chrome or uncoated alternatives. Note that O2 sensor wire extensions (BBK #1676) are required and sold separately.
