The flanges will not mate up due to the difference in size and the bolt holes.. I love my gtm kit and praise gtm for all of their hard work put into this kit btw...( I know Iam no where near as good as spohn with the brown nosing but I am sincere)....

It may not be a smooth transition, but I believe you can bolt any exhaust to the 3in DP.
It depends on the exhaust/ flanges. I have a Greddy TI-C which is a 70mm or 2 3/4''. I'm not positive but a friend of mine that has experience with GTM kits and has done several lately that in my case the 3'' downpipes will work with the Greddy kit unless GTM hs done something different lately. If not I'll make it work. I know in the 350Z days there were tons of GTM TT kits with Greddy TI-C exhaust combo's.
