Coyote Swap Longtube Headers 1-7/8 (fits 79-04 Mustang) Ultimate Headers

     Ultimate Headers’ Engine Swap Headers are designed to make installing a later generation engine into an earlier vehicle a much easier job… with great eye-appeal! This high-quality header set is designed to fit Coyote engines onto UPR modular engine K frames for Fox Body Mustangs (2005-79K-MOD-100-50, 2005-79K-MOD-100, 2005-79-MOD) .  Cast Stainless Steel flanges and the tight radius cast Stainless Steel elbows lets you put large tubes in tight places! The strength of 321 Stainless Steel tubes delivers a stronger, more durable header than our competition. Plus, you get a complete package – headers, ARP 12-point Stainless Steel header bolts, a pair of matching Cometic HTS header and HTS Collector Gaskets (if applicable). 

 

10R80 headers should be used with a Gen 2 or Gen 3 Mustang starter. Gen 1 starters are bigger and will not clear the headers.

 

Select the appropriate header for your application from the drop down menu.

 

Ultimate Headers’ Low-Profile Connector Clamps provide a highly useful solution to connecting exhaust system tubing when ground and/or body clearance are problems.

Cast from the same non-corroding 316L allow Stainless Steel material as the Ultimate Headers header flanges and collector flanges, these low-profile clamps are engineered to stand up to heat, stress and vibration of high performance engines. Additionally, these low-profile connector flanges add a special level of quality elegance to the header-exhaust system installation.  Select the clamps from the drop down menu to add them to your order.
