Let your Coyote conversion sound the part
A Coyote-powered Mustang or Capri is a car you build to enjoy. Kooks 10504102 brings the exhaust sections together in one 3-inch Race package, with the front connections, crossover, mufflers and turndowns supplied for the specified conversion.
SKU: 10504102
The exhaust sections come together
The 16-gauge 304 stainless package includes front connection pipes, an X-pipe, tailpipes, mufflers, turndowns and all clamps. The exits sit ahead of the rear differential, within 12 inches of it, giving this a distinctly different layout from a rear-bumper-exit system.
Match the headers and transmission
Use 10502202 or 10502402 headers for the specified 10R80 / 6R80 / MT82 installation with the OEM bellhousing. The original transmission-crossmember mounting brackets must be removed, and a Stifflers crossmember is recommended.
Custom supports for a custom car
Have your installer make the exhaust supports for your conversion. Hangers are not supplied. That work lets the exhaust follow the engine and transmission position in your car, with adequate clearance around the driveline and body.
Matching products
The Coyote-swap headers match this exhaust with the specified 10R80 / 6R80 / MT82 and OEM bellhousing; plan for the required chassis parts and custom exhaust supports together. This header route is designed for a Maximum Motorsports MMKM-2.1 K-member and standard 4.6L mounts (6-504-BL), using a 1997-2000 Mustang 4.6L starter (SA848RM or equivalent). It excludes 2015+ Coyote engines retaining Charge Motion Control Valves, Ridetech SLA airbag suspension and an OEM rubber rag-joint steering shaft.
