SCG Tips:
-DO NOT run the graphite gaskets that Speed Engineering supplies. ONLY run OEM MLS gaskets.
-Replace the motor mounts during header install. It is a good time to do it and will ensure proper fitment of headers to the engine bay. We sell and stock BFW engine mounts.
-Be prepared to deal with broken factory header bolts. The easiest way to remove them is to weld an M8x1.25 nut to them and back them out. Use ARP bolts when installing these headers.
