Some of you may think this is ghetto, but I had it done and it works perfectly to resolve interference with the subframe.
Cut a slot in a large washer, and slip it between engine mount and frame. This raises whole engine a few millimeters, creating clearance for the overpipe. Takes 10 minutes and any muffler shop can do it. |

Make sure the rest of your exhaust system is not introducing a stress onto your ace header, causing it to be torqued.

I think the overpipe contacting the subframe is the biggest issue. It clears by about 3-4mm, but makes contact on hard left turns when exiting with throttle.
Washer trick under engine mount solves this issue by raising the overpipe another few mms. Sent from my iPhone using Tapatalk |

So im in the middle of changing out my FLywheel, CLutch ect and have my head up behind the engine. Noticed the exhaust manifold stud is touching overpipe. Anyone else notice this? could be another source of rattle

You can put a shim on the motor mount or maybe its just old and saggy, like my neighbors ahem*. Probably easier just to cut a little nub off that stud.

You missed the post above I have Perrin mounts. Yeah will just cut off that knub when I swap to stock headers for upcoming inspection. Just something for others to check since you cant really see it from looking from the front of the motor.

I dont know how many things can cause the cylinder head to shift relative to your overpipe/frontpipe junction. Was it always like this? I cannot imagine the perrins being different dimensions as stock, shorter?

The perrins should be the same. PLus the cylinder to header to overpipe should remain constant even if the height was slightly different. Front pipe was unattached as well. I really don't have any rattle its just something I noticed with the Tranny out of the way I was able to stick my head up behind the engine.
