BBK Adjustable Clutch Cable and Aluminum Quadrant Kit for Ford Mustang features Coyote swap long tube headers which have a mandrel bent high flow 1 3/4 inch tubing with 3 inch collectors. It makes them perfect for both n/a and boosted builds. The space constraints make fitting a 1 7/8 inch header very difficult. Especially with the need to accommodate Ford's chassis revisions over the 25 year span of the Fox chassis. These BBK Mustang long tube exhaust headers are now available in the chrome and silver ceramic coated versions. The stainless may be available depending on demand or by special order.
