i say 4.10 or 4.30 gears. tune and midpipe.

these cars have a 6800 rpm redline, they need all the gear they can get. and they dont mind reving at all. i have 4.10's in my GT and DD it and it doesnt bother me

 

welcome to the forums, nice car, get some gears in it and go from there, if you want a louder exhaust youtube is what you would want to use to figure out what type of exhaust you want, keep in mind that power is no good if you can't control the car (upgrade your suspension)

You should read up on suspension a bit first if you dont know what you are doing. as for power things, I'd say the gears would be a nice place to start.

 

hey. welcome!! and i have to agree with some of the other people, pictures are needed. and it seems like these guys have already given you a lot of good advice as well.
