The CTI should produce the most power and torque, and there haven't been ANY complaints that I've seen from anyone who has it.

Pacesetter has a header as well. Mine just came in the mail today. Got the ceramic/armor coated one, very nice looking, nice welds, great quality. Just got to get it on along with my Cobalt Addiction DP and GMPP Exhaust.

*Edit: Just realized it said "one more downpipe" not header.

NO AND NO!

you really dont want a catless DP installed by a dealer, they cannot remove emission eqpt unless it is being replaced for warranty....

I had it done thru CTI as an option
I would put a cat on for warranty unless you have a cool dealer beyond cool
If you have the dealer modivy the cat they will probably void your emissions and powertrain wty

***** builds the CTI headers to order, so expect at least a week to 10 days for delivery, but you get an excellent product. worth the extra price and wait IMO. I gained about 13 hp and 5 tq with my setup (before tuning, 26 hp/ 12 tq total gains after), but it definately woke the car up. I've got the dp w/cat and it's loud enough already, can't imagine how loud it would be without...

I ordered my CTI with a CATLESS downpipe. I honestly think it will sound good with the Corsa Touring, however.

The downpipe is something I am completely undecided on as well
Doing the GMPP manifold with my GMPP catback, but not sure about the downpipe. May leave it stock for a while

Exactly, go with the XTC DP from CA. Don't keep the stock DP it's garbage.

Good point, but I really don’t know what to get at this point. I’ll keep watching for everyone’s reviews/ dyno numbers

Dyno sheets please. 13 hp with 5 ft #'s is just about imposible.
