Filters can't do much unless you change the exhaust as well. It's better to keep it stock, it's a family sedan with a CVT transmission designed to get you from point A to B, I'd advise you to not go Vin Diesel on it. If you decide to take this path, you'll need to replace major suspension components too so that Corolla's famous bodyroll could be tamed and if you want to go fast you need to stop fast aswell, so an upgraded braking system aswell. If you just want to go fast in a straight line (like "racers" do here) then suspension can be neglected. It's not an easy path, I'd advise you to spend your money elsewhere.
