There's also some discussions about the OFH header flange not aligning with the overpipe causing exhaust leaks. I'm trying to find more threads about it, but the link below is the first I've found. I also remember seeing another thread about the pipe diameter between the OFH and stock overpipe. Something about the overpipe diameter being slightly smaller causing weird noises and exhaust to not flow as smoothly.

Most fitment issues with decent headers are caused by installer.
they dont use new gaskets , will almost always leak
dont clean up 02 bung threads with tap\chaser, will strip 02 sensors and leak
over torque bolts causing flanges to warp, poepol ofen do this trying to stop old gaskets leaking.
dont loosen midpipe to allow overpipe to header flange to line up without stress
catless header will be louder than stock due no cat and often made of thinner lighter material than stock and dont have heat shields, so they sound different
have a read of the Basic Bolt on mods link below and read the links to header install in that post.
