Hey guys--need some quick help here.

I know the stock exhaust down pipe of the GN/TR necks down at the connection of the turbo and then opens up to approximately 2.5". Does anyone have one laying around that you could give me the inside dimension? I'd do it myself but my car is currently out of state with my father...long story.

thanks,
GS

Mine measures 2 1/8" on the inside and 2 1/4 on the outside. This is on the end where it necks down to meet the turbo. Hope this helps.
