port and polish?
 

woulld it be worth it to port and polish my exhuast manifold. rather then buying an after market header?

The runners should already be port-matched to the head... porting it wider wouldn't do anything because the exhaust ports on the head would be the bottleneck in the system. You only need to port your exhaust manifold if the runners are too small for the ports in the head, such as if you port/polished the head, resulting in larger exhaust ports on the head and making larger manifold runner ports necessary.

You might as well just get aftermarket

okay, thanks for the quick responce.

so now i am in the same boat as before...i need to by a cat for the ex conversion

and you cant buy them in california....cept from the dealer and they want 600 for one

should i shop around on craiglist?

just goto junkyards and look for an ex cat

they arent aloud to sell them in california...junk yards arent aloud to sell the cats here
every where i call says they cant sell them

buy a magnaflow high flow cat? might not be legal in cali tho

its illegal cronic. but do you know if i do that if it will not cause my cel to turn on?

Using the Magnaflow cat should keep the CEL off. You just won't pass visual inspection if they notice it's not OEM or CARB approved.
