If you want to remain catted, I would highly recommend our catless downpipes + catted front pipes combo. The cats are moved downstream and reduced EGTs tremendously!
Going full catless is fine, we've found a work around to include microcats and not trigger a CEL. However anyone considering a catless system should pair it with a tune. The ECU restricts this car a lot!
Here is a link for more info:

thanks for your post, im definately interested. one thing for sure, no one can accuse you of fudging your dyno resuts to show bigger gains. 7 hp gain for all those mods. of course the question then becomes, is it worth 8-$9000 in upgrades for 7 hp?
i already have a tune. so ill have to check with my tuner to see if maybe it needs to be tweaked.
for catted version II, are these 200 cell cats?
btw, i thought dynos only showed wheel hp?
