I have the hookers Part# 70501364-RHKR. These are also Holleys. installation was ok . Had to modify some the rear control arm braces. I am surprised it does not hit anywhere or rattles at all. It is quieter than before when it had Dynomax mufflers.

For me the biggest issue was, since my car is so low. The left side pipe from the X to the heather dips. This is done for those that have the stock cross member that is closer to the ground on the left that it is on the right. That dip for me was too close to the pavement. I had to cut that part and replaced it with a straight one. Since I have an aftermarket cross member it then fit perfectly and I was able to bring that pipe closer to the car. Additionally since my headers are not hooker we also had to modify the collectors part. Bottom line, depending on your application, welding might be required. I am attaching some pictures.

I have an 86 regal 383, modest 450 hp. Full 3in mandrel bent x pipe and flow master 40's. Go 3 in. The sound is sweet and different.
