Tti 1 7/8 headers
I did the TTI 1-7/8". If you are using an aftermarket shifter with the cable coming in from the front (traditional), one tube is directly in front of the shift lever. My collectors pointed to the center of the car , not straight back. The install was ok, but I have an HDK set up and no inner fenders to deal with, the column will be the first thing to remove though. It took longer to design a cable system to clear the one tube for a B&M shifter cable than the header install itself. I used the Milodon 30940 pan.
