Also u can do cat-back or full exhaust depending on how much u r
willing to spend. A low cost mod to your car could be an air intake

help through the mid rpm ranges but suffer in acceleration. It
works by increasing the amount of air that is sucked into the
engine. When you floor it you can easily tell the difference.
