is this a good deal

it depends on what you do, cuz if you can afford the pipe then you will be much happier, tires help alot but still for power the pipe is better, you will only gain a little with tires. if you just dont want to get stuck then get better tires.
 
didnt work, but like tryingtobefaster said, a pipe for performance gains and tires for a traction gain, tough call for first upgrade!!
