hey guys, I need some opinions on what mod I should do next for my car. So far I only have cold air intake and gst muffler put on and am not sure what will be the best thing to do next. I'm kinda thinking about either getting a UDP or headers next. Which one of these would be more effective for my quartermile run? Also if anyone has any other suggestions on what I should do next (i only have about 200 dollars) plz feel free to tell me. I'm mainly just looking for something to help boost up my accel since my speed off the line is so damn slow.
