I have put a 60 mm throttle body in the place the 55 mm throttle body, a K&N filter in the place of the stock filter and a 2.5-inch cat back exhaust in my Mazda 3i. It runs and drives good with these, but I want more. Is there anything else I can put in the car to make it run and drive better without spending a ton of money on it?

Thank you for your time,
Daniel
