What are you guys doing to your Hookers??? I autocrossed mine for years using 23" diameter tires and the car was low! There was even a speed bump in the tech line area!
I'll disagree on Hedman's fit. My experience(I'm sure the pictures are still here in archives) the 1 3/4 the flanges were 1/2-3/4 " off from end to end. Both rear tubes hit the firewall-not the AC box-firewall Collectors pointed at some angle not straight back-Hedmans answer when sent back-You must have moved the engine back, they fit out jig.We cut off 2 tubes and remade them and pointed the collectors in a better direction.
Hedman 1 3/4-1 7/8 based on their 1 7/8- both collectors pointed at the transmission and would not have fit a vehicle. At least that they did agree and repair them. Flange was flat though
