put a cold air intake on it, then replace the header, exhaust piping and muffler and hollow out your catalytic converter. you could gain upwards of probably 20+ horses out of that. putting bigger exhaust usually won´t help torque though. My advice is before anything, learn about what you already have. appreciate it, caress it, love it. That way you can figure out the right ways to make it work better to your liking.
