Kooks Headers 11313500 2.5" Catted H-Pipe 2005-2010 Mustang GT 4.6L 3V

The Kooks Headers 11313500 is a high-performance 2.5-inch catted H-pipe designed specifically for 2005-2010 Ford Mustang GT models equipped with the 4.6L 3-valve engine. This mid-pipe section features integrated high-flow catalytic converters that maintain emissions compliance while maximizing exhaust flow and performance gains.

Key Features:

• 2.5-inch mandrel-bent tubing for optimal exhaust flow
• High-flow metallic catalytic converters maintain street legality
• H-pipe design balances exhaust pulses for improved performance and sound
• Precision-engineered to work with Kooks long tube headers (required)
• 304 stainless steel construction for durability and corrosion resistance
• CNC machined flanges ensure leak-free connections
• Handcrafted in the USA with over 50 years of exhaust expertise

This catted H-pipe is designed as part of a complete Kooks exhaust system and requires Kooks long tube headers for proper installation. The H-pipe configuration helps balance cylinder bank pressures while the high-flow catalysts provide significant power gains over restrictive factory catalytic converters without sacrificing emissions compliance.

Note: Requires Kooks long tube headers for proper fitment. Professional installation recommended.
