I have been the owner of a 2003 Cobra and have 51000 miles on it. It has a JLT CAI and I have recently order an entire SLP exhaust with long tube headers and loud mouth II catback. Also ordered a RAM Powergrip clutch with new billet steel flywheel and Steeda Quadrant. Wondering if and which pulley to change to?? Also have the Diablo tuner for the past 10 months. Any info would be appreciated. Thanks in advance. :burnout:
