Fitting TTi headers on a 273

EZ, just run a 1/8 mounting plate with 273 port sizes.
I haven't seen the current version but in my experience sadly there is no room to do this.
I don't think its been changed that much if at all. But I was an early guinea pig.

You can see how close it come to the rail here.
There still needs to be room for the head pipe to make the turn which also has to clear the t-bar.

This gives some idea of the room to t-bar.

Again the design may have been slightly changed since then, and my car just may be 'special'.
