Is your car lowered? This really changes the rear geometry. Much better anti squat but the roll center moves too much and is too high.
A Watts link fixes this. The Fays2 watts link allows for the exhaust to come out in the stock locations. Right now I just need the time to burn it all in.
I am welding in a Fays2 kit right now and the mock up cleared my dual exhaust. The pipes ran too close to the rear axle and I have to redo them (in 3 inch size) and they will exit in the stock location. If they ran up a little closer to the body I would have needed no modifications.
Now it's an excuse to redo the exhaust: 3 inch x-pipe with magnaflows exiting under the rear bumper is the plan.
