i have an '04 cavy. i have installed the rksport lower engine mount, rksport intake, i have an aftermarket catback exhaust system, im planning on getting the upper motor mount too. is there anything i can do to squeeze some more power out of my car without voiding the warranty?
Well remember how your warranty works is if you modify or change a part, they have to prove that the part has caused whatever problem you're having. Now if you open your motor and change anything, you void your warranty for your engine, yes. If you open your transmission and change anything, you void your warranty for your transmission etc.
Also, power gains depends on how much you are willing to spend. If you really want to know what you can do to your ECOTEC, please read the

If you only have a cat-back exhaust, the next step would be to slap on a header and high flow cat.
Yes I would also agree a header and a cat. Pacesetter for the best bang for the dollar.

header, high flo cat, bigger TB, set of cams, if you have an auto get a autotrans interceptor, if you have manual, get a new clutch and flywheel
