Test fit
I bought turbo exhaust flanges from JEGS and the diameter of the port holes were 1.75". My MN12 Kooks headers have the 1.50" primary. I bought a steel tube from a welding shop with an OD of 1.75" and an ID of 1.50" perfect, only $5, they were going to scrap it. I cut the steel tube into 8 rings to have welded in the flange so I could match the 1.50" primary. I than had the headers welded on top of the flange. I just got them back this week and did a test fit, they are golden. The driver side is a little tight but it will work. I also had a extra O2 bung welded in for my wideband. So they are done for the most part, I just got them back from the machine shop. After all the welding, the heat will warp the flange, so I had them flatten the mounting side. Next week I'm having them ceramic coated.

These are for Cobra rotors in the rear. I also did a Mustang 4.50 hub swap and bought new UHMW knuckle and lower arm bushings for the rear. New Cobra rotors and pads, braided brakes lines, Reman Corvette calipers, Reman rear T-Bird calipers and wheel spacers for Mustang rims.
Man these are cool! Can't wait to have these in. The speedo is GPS, no VSS to plug into. Turn signal and flash built in. Made in the USA.
