yes the Titan will defo mate up to any y-pipe including the Titek. we have Titan's in stock at the moment, but alot are going out to europe, USA & ME.
If your have an EDM model GT-R and want the legamax bear in mind the prezel design will hit the edm fog light and need removing....
This I can confirm myself as I installed the "pretzel" design on my EDM gt-r. The foglight will not be the only problem... The tow hook fixture will also have to be heavily modified as well the system itself will need couple of welds to "correct angle" and make as much room possible near the bumper grille. So quite a "project" if you want it nicely done. Better I would have gone for GTC TITAN from Ben if you ask me.
