I have rotated mounts, hann DP, test pipe and exhaust. Seems that with the rotated mounts, if i remember correctly, they rotate the motor, intake manifold down, exhaust manifold up, which has caused the cat back and test pipe to be slightly out of alignment and now, up into the bottom of the car which causes rattling. All this can be corrected with a longer DP with a slight bend angle change. Just wondering if anyone has encountered this and if anyone knows of a longer DP to correct it. Assuming that when this kit was made, it was done with stock mounts in place. I can make a custom DP but would rather find one as im limited on time.
