1 5/8" long tube headers designed for Ford's modular 4.6L 32 valve engine. Fits both Mach1 and Cobra. These headers feature CNC mandrel bent 16 gauge 304L s/s tubing, 3/8" thick CNC laser cut flanges, 3" collectors. Designed to bolt up to Stainless Works exhaust or work with factory or aftermarket exhaust with minor fab work. Air tube fitting and O2 bungs installed.
I was a little hesitant to purchase at first with not wanting to install a tublar k-member and running a 4r70 trans in my 04 Cobra... These SW headers by far exceeded my expectations for quality and fitment and sound.... The install was done on a lift with me and a mustang buddy in less than 3 hours from start to finish dropping the stock k-member.... OH did I say the fitment with the stock k-member and the auto trans was perfect !!!! Great product I HIGHLY recommend !!!! (Posted on 8/22/13)
