You can't run catless unless you get a custom map. The OTS maps are designed to work with a catted DP.

Go to Jorge at PandL. He has done wonders on all of my cars and has personally taught me much about tuning. He is a great guy and really knows what he's doing with the 08.

For an OTS map, it won't really matter if it's catted or catless. Either way it's not optimal.

Besides the "green" differences between catted vs catless, what other differences can we expect from both (performance, hp, tq, sound, etc?).

I haven't bought one yet, but right now, I was leaning toward the Cobb DP. Seems like it would work best with the Cobb OTS Stage 2 map. I also want a catted one.

I thought a catless pipe with a Cobb OTS map would get a bit of boost creep.

I ended up going with the MadDad divorced catless Dp with Cobb stage 2 93 oct map so far muchbetter performance and easy install everything matched up perfect. Today i tried out the Cobb Ap dyno feature in 4th gear set it to start @3000 rpm and end @7000 keep the weight of the car the default that Cobb has in the Ap after the run hp was @430hp and tq @364 i am not saying that MadDad is the best to go with but i def like it. and yes the OTS map from Cobb has a code defeat for running a catless Dp
