But geez, the majority of 300plus Ts have so much mid range torque that loosing some isnt a major issue. Link to comment Share on other sites More sharing options...

Geeseman Donating Members 1,805 Member For: 21y 1m 2d Location: Sydney Posted 23/01/08 02:22 AM Share Posted 23/01/08 02:22 AM 4inch xforce one has been bolted onto my aps exhaust. Made 385rwkw with it and 385rwkw with the stock one. Im sure the zorts is a little louder now as well.Autotech had run over 400rwkw on their stock turbo falcon unless you want over this I'd say it's a waste of money Link to comment Share on other sites More sharing options...
