I installed unortodox pulleys on my car, few months ago. Ever since, my belt is slipping badly under 2000 rpms. Tried everything, but nothing works. I got 2003 EX m/t. Just wondering if anyone has these on and if they do, what kind of belt did they get (brand, size etc.) anything that could help me get rid of this annoying problem. Thanks.

Slipping???

You need a smaller belt...i think you got the wrong belt size

I went a belt smaller then what was suggested. And its still slipping. Im confused about this thing, its coming to the point where I wanna throw back the stock pulleys, but then again I had fun with these and I did notice a small gain while downshifting at high speeds. Anybody with correct belt size # out there, please ?
