AT600 Package ..what next ? :-)
I currently have the auto.torque 600/stage 3 package which includes the following ......
Full miltek exhaust system
Hi flow k & n air filters AT 80MM MAF intakes and housings
If i add downpipes and ansu injectors to stage 4.25 will i have to upgrade the gearbox as well ? Circlip upgradea gear.stops.etc ?
I have spoken with a garage for a price has anyone just went to stage 4.25 and is.it worth.thr extra bang for buck ?
Mainly wanting downpipes for a better grumble noise on exhaust note ..has anyone installed downpipes and remappped without larger injectors or gearbox upgrades ?
