i have a 2005 mustang gt premium with headers tune exhaust intake and the like, the guy before ,e swapped out the stock 4.10's to 3.55's (have paperwork to prove it) any idea why he did this? would i be better off switching back to 4.10's? thanks
yeah, the car is mostly stock, i just plan on doing CAI, Headers, H-pipe, Gears, Edlebrock intake, 70mm TB..... so would a 4:10 be good, or should i go with a 3:73??
