from what i know, the DC header doesnt really do much, other than add a tiny bit of hp on the top end, while hurting the power at low to mid range rpm. did you notice a gain?

and yes, you will get a louder exhaust note by going cat-less. i have yet to hear a cat-less celica in person... i did hear the kazuma, and oh crap, does that thing scream at you!

as for cutting and welding... i dont think you need to do any of that, unless you're doing a custom setup. i'd say it should all be just bolt in.
