JLT all the way,You might as well get the SCT tuner and a smaller pulley at the same time-You must have a tune either way>And the result is oooohhh so good!!!
I had JLT, got tired of it rubbing and the look of Carbon fiber. Bought a C&L and had it painted.
Most of the reasons lie in the fact that my Bangastang radiator shroud didn't fit well with my JLT. I'm happier with the C&L and the fact that it's cast aluminum.
All in what you want I guess. I'm not a fan of Carbon Fiber (Importish)
