TFS heads + MAC headers?

OMAR · 09-03-2003, 07:22 PM

Anyone have problems getting Mac 1 5/8 equal length headers to fit TwistedWedge heads? I left the headers connected to the exhuast when I removed the old heads, so I didn't trial fit them first.

Any good or bad experiences, I'd like to know.

I had Mac equal length shorties and now, Mac full length headers, and no problems to speak of with my TFS TW heads..

The bolt holes don't seem to be lining up. The Mac's dont have the one piece flange so they can't be warped. I'll try again tomorrow.

If they aren't of a one-piece flange construction, then they can be slightly out of alignment. Just screw in as many of the header bolts that you can and then use a pry bar to help line-up the remaining holes.

yea what eric said, my friend used mac lt's and tfs, he had to pry on the individual flanges.
or try unbolting them from the h-pipe, then installing them.
