HEY guys, I just got some BBK underdrive pulleys for my 97 gt. Do I need to buy a different size fan belt or will the stock size work? Also, I got a magnaflow exhaust with a o/r x pipe, C&L pleneum with 75mm t/b,BBK cold air induction, BBK c/c plates, with Tokiko shocks and struts, What can I expect when I install the pulleys & What mod do you guys think I should go for next???? Thanx for the help..
