Since the M2 IC's won't work with the efini y pipe, what do you do? Does this mean you can't use the stock y pipe or just not the efini one thats metal? And also a question about FMIC's, is the stock front end to restrictive than an aftermarket one?

Garfinkle made his pipe from a piece of Alum tubing from Burns stainless ( company name ) and a flange he made out of alum. He had it welded , then polished it.EASY EASY

I wasn't aware the the M2 SMIC wouldn't work with the Efini Y pipe. What's the reason that it won't work if anyone would be nice enough to fill me in on that one?? Well, thanx for any info that you guys can give me. Laterz.

The reason there is conflict with the M2 intercoolers and the Efini Y-pipe is simple:

The M2 intercoolers inlet tube REPLACES the cross-over tube and couples directly to the Y-pipe portion. This works on the US version because the y-pipe couples to the cross-over tube already. However, with the Efini Y-pipe, the cross-over tube bolts to the y-pipe section instead of coupling with it. You should now understand the conflict.

I had the efini and it was just cheaper and easier to put the stock one back in and use a new coupler. You have to do some serious cutting and reworking.
