Put the exhaust into the plan for your Coyote conversion
A Coyote-powered Fox Body or SN95 can be a brilliant car to own. These Kooks headers are made for the specific manual-transmission conversion arrangement below, with 1-7/8" primaries and 3" outlets. Match the mounts, starter, steering and crossmember together for the installation.
SKU: 10512402
Use the specified conversion hardware
10512402 is for manual transmissions with an OEM-style bellhousing. It is designed around the MMKM-2.1 K-member, standard 4.6-litre mounts such as 6-504-BL and a 1997-2000 4.6 Mustang starter, Ford SA848RM or equivalent.
Allow for the chassis changes
The OEM transmission-crossmember mounts must be removed, and a Stifflers crossmember is recommended. The headers exclude 2015+ Coyote engines with charge-motion-control valves, Ridetech SLA airbag suspension and the OEM rubber rag-joint steering shaft. Gaskets and header bolts are included.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Talk to us to discuss the right tuning route for your vehicle.
