The Kooks Headers 11543200 is a 3" x 2-3/4" catted stainless steel X-pipe engineered specifically for the 2015-2020 Ford Mustang Shelby GT350 equipped with Kooks long tube headers. Constructed from 3" mandrel bent 304 stainless steel tubing, this mid-pipe section delivers exceptional exhaust flow while maintaining emissions compliance with high-flow tuner catalytic converters.

Key Features:

• 304 stainless steel mandrel bent construction for maximum durability and corrosion resistance
• 3" x 2-3/4" OEM catted connection with integrated high-flow catalytic converters
• Connects to OEM exhaust and retains factory mufflers for a bolt-on upgrade
• Improves horsepower at all RPMs through optimized exhaust scavenging
