Well, after a week of fighting schedules and weather, the MAC headers are finally on the car. Fired it up w/o the y-pipe and its sounds pretty awesome. Really easy install. Only problem is the y-pipe isnt in line but that's the least of my worries.

My question is what have others used to plug the A.I.R. holes on these headers? It was decided that we remove all this after we were into the install. Having some problems finding a fitting to match the thread.

Thanks.

 

M22 drain plugs work for macs.... but what I did was just have the exhaust shop cut them off and weld them shut... the did the egr tube on the p-side header also... looks good and no leaks.. and looks better than two stupid pipe plugs coming out of the headers.

 

Mine are plugged by some pretty damn big bolts we found that threaded down into the holes.. and some jb weld

You should get them cut off though, thatll free up a lot of room in your engine bay

 

How does the muffler shop cover up the hole? Doesn't that ruin the coating?

Thanks for the replies. I was hoping to just find some bolts to screw in so I would not mess up the coating. But I may do the shop thing too. Any other suggestions?

Thanks
