Is the GTLW piping 50mm or 60mm?

[whatisreal7]

SOS website says 50mm, but some owners are saying 60mm. Any other owners can chime in on the true inner diameter of the GTLW piping?

Dali sells adapter pipes for the GTLW that is 50mm, so if in fact the GTLW is 60mm, doesn't the constriction of air compromise performance?

Lastly, what is the main difference between a 91-96 GTLW + adapter pipes (to fit a 98), as opposed to just buying one that fits 97+? Is there a trade-off in performance/weight/price? The reason is there is a 91-96 for sale, and I have a 98, and was wondering if I should just buy the one that fits the 98 outright as opposed to using adapter pipes.

I believe all GTLW exhausts are made for '91-'94 NSXs. The exhaust fits '95+ NSXs with the appropriate adapter pipes.

GTLW sizes:

Diameter of the main pipe = 60.5 mm
Inside diameter of the main pipe = 58.5 mm
Inside diameter in flange part of piece = 50.8 mm
Adapters inner diameter = 50.8 mm
