No , i have the stock Heat Exchanger on the car still, what Heat Exchanger would you recommend ?

Hey man i have the same set up as you did ( 2007 cobalt ss s/c 60 lbs injectors and a 2.6 pulley ) I am also getting random misfires and at idle it will go from 860 - 1010 rpms . i was wanting to know how you fixed the problem, i have already gotten new plugs and a new cat ( old cat broke ) also got an oil change. Any help please ?

also i got NGK step colder plugs gaped at 0.32

Hey I saw that you have a MOMO Hand brake. Espacially the one I want. Is this the right link to it.

I was looking at the pic of your car and wanted to know how you did the smoked headlights. My car looks almost identical to your (sans the rims) and I'm diggin how your headlights look.
