Woggster Member 15 Member For: 15y 5m 6d Posted 21/04/09 11:32 AM Share Posted 21/04/09 11:32 AM (edited) I would also like to know how much power you would gain from those mods aswell.I was thinking: exhaust, typhoon intake, under drive pulley just to make it a little more driveable If I do these mods will there be a loss in fuel economy or driveablity? I'm assuming I'd need a tune to get everything running properly Edited 21/04/09 11:35 AM by Woggster Link to comment Share on other sites More sharing options...
