Custom intake manifold questions...

[J. Fast]

Looking for some empirical data on Xcessive Manufacturing intake manifold for the Galant platform. Are there ant members on this board that have pictures and experience with XS manufacturing and the intake manifold designed for the 6g72 and 6g74/75?

It's pointless unless you're pushing a 3.8 to the absolute max.

^^^ Not a 3.8 but 6g72TT

I've got the power :). I want the RPM range the manifold runner design offers and to upgrade to a Q45 80mm+ sized TB or larger. My current setup has a restriction at the throttle body. I step down 1/2in diameter at the TB off the intercooler piping. I'm also looking for a USDM drivers side dump for a single turbo conversion on one of my other vehicles.
