phat shaft 62 ordered!
 

well i was just wondering how big of an upgrade it is to go from a stock exhaust manifold with a 56mm 12cm housing hx40 to a 3 piece quick spool and a 62/65/14 phat shaft turbo. will i see a big difference in power over the hx40 as well as spool up? im hoping itll help take care of my excessive smoking too
