Hey everybody, I'm designing a custom Y-pipe-back exhaust for my Z33 and I want to eventually upgrade my stock Y-pipe to the Motordyne XYZ. In order to match my 3 inch flange to the Motordyne one, I need to know the center-to-center spacing between the two bolt holes. Can someone measure this on their setup? I imagine the spacing will be the same on the XYZ and a stock Y-pipe? Do all the 2-bolt flanges have the same spacing on a Z? If it makes any difference, I'll be buying the resonated XYZ. Sorry for the question overload; thanks in advance .

PS: This is the flange I'm thinking of using: http://www.summitracing.com/parts/vpe-1473s/overview/

 

That one will work, they have a little room for error built in.

 

Should be the same measurment you'd find on the rear section of your OEM exhaust, since I'm fairly certain the XYZ is a direct bolt in replacement into an OEM system.

 

Actually the Motordyne setup is 3 inch and stock is 2.75 inch . But they do work together.

 

Ah, true ^ forgot about that.

 

Thanks for the info guys . I'll post the finished pics/sound video once it's done in October.
