Has anyone ran into the problem after installing the MSA's 6 into 1 header of the transmission mount interfering with the 2.5 inch piping ? If so please give me some ideas:disappoin I really don't want to have to dent the pipe there to gain the 1/2 inch clearance!

I think you'll find that MSA sells different shaped headers for different transmission types. Perhaps you bought headers for a manual transmission, but have an automatic? (or vice versa)

Always worth checking.

I've heard of this before by another member, maybe about 4-6 months ago. Try doing a search. I can't remember what the outcome was.

I just finished going through the same thing as you. Here's the link:

I would suggest you speak to Sal at MSA (x201). It's hard to get him live, but in the end he did the right things for me.
