Custom alternative to Test Pipes

Is that 2.25" or 2.5", looks like the diamater is a tad smaller than OEM. Not sure if it would make much of a difference.

Guys, pipe ID's are equal. No restriction here.

I will do this next thursday on my car, or to be honest a company will do it for me :-)

But they need to know the stock diameter of the pipes AND the cc between the bult holes in the fitting to the downpipes.

Can anyone help me out with that?

I can measure this for you tonight since I have a stock X-pipe. As for the fittings, I would re-use them, if you try to build your own, it can be hard ot ensure proper fit. If you use the fixture and re-use stock fitting, the fitment will be spot on.

OK, here you go. Distance between center of holes is 3.8 - 0.43 = 3.37 in. Pipe OD is 2.55 in
