I was thinking of going with a new cam pulley.

I was wondering if cobb is a good company to go with in that department.

Also, its pobaly not warentee friendly right?

What performance gains will i see on my ej25t?

thanks

 

I didn't know COBB sold cam pullies for the STI. They have crank pullies which are lightweight and not underdriven. I am using Vishnu's underdrive pulley in my WRX and am having good results with it, but if you are looking for cam pullies, then that's irrelevant.

Good luck!
