Remap is definatly worth it i would reccomend jabba as you actually get a printout of your power some of my mates have revo maps and you say how much hp you running and there like i dont know?? whereas i got a priuntout when i had mine done got a full custom map for around £400 best mod ever. don't worry mate you wont need to clean it quite as much as me the standard exhaust sticks out a bit and is slashed the miltek is in line with the bumper and isnt slashed to the smoke just goes straight up the back. first mods are pd160 intake and green pannell filter cheap to do makes the turbo whistle a bit more which is nice and slight power increase.
