You want to increase your power throughout the RPM range? Like make it go faster and feel more powerful the more you step on the gas??

I put the kakimoto intake chamber, and put a K&N Filter, i put a Duramas sport final exhaust (similar to Remus), but i think that the middle exhaust just after the catalyzer, is the problem, because i think that i missed power, and is not normal situation.

Thanks.

Does the resonator even restrict all that much?
You can replace it with a straight midpipe.

you can increase the diameter of the exhuast, although you can also increase it to much. The 2.5 n/a motors seem to like right about 2.25" to 2.5" with your engine you may want to stick with 2"-2.25" exhaust diameter. Post some pics of your car btw.
