    +1. The boost control between a catted and uncatted is fairly substantial. You may be getting some pretty severe 'boost creep' without the cat as well. In that case... See the EWG part of the install =)

    I'm running catless dp with stock catback and have no creep issues. I recommend ewg though. That's what i'll be doing.

    Very nice write up. Subscribed!

    Just purchased Invidia catted downpipe and will marry it with Nameless CBE. As far as I know they're both 3 inches so install should be straight forward. Do i need additional gasket though? Would like to order everything first before I do the installation.

    You should only need the gasket that comes with the downpipe. As for the entire marriage, Vegas is the place to get it done for cheap.
