The only thing in a header you can put onto the car is a shorty header. If me & only was looking to do this I would just keep the stock exhaust on it since it is a z06. Robert

Thanks for the response. That’s what I was thinking after more research. I was able to do mid lengths on my 02 Saleen and still pass emissions. Just don’t think it’s possibles here in Oregon these days.

A few guys in here DID use the stock Z06 stuff then ported it out some on the inside of it THEN had a shop to do the coating on them on the inside & out & said did get just a few more rwhp from them. I really would do this then to spend the money on a shorty header, Plus it will still look stock & the Z06 stuff is better & liter. Robert

Where in Oregon? I think Portland is the only area. No emissions here or on the coast. Portland is going crazy anymore I moved out of that area.

I’m in Forest Grove and work in Portland. Trying to plan ahead on my build. I’m going to most likely upgrade the blower to the Heartbeat when my warranty is up.

Your only truly legal option is to retain the factory catalyst in its stock location. That means a stock exhaust manifold or a CARB compliant shorty. When you look at the Z06 manifold, it actually flows quite well and is not the bottleneck. Upgrading to longtubes typically only gives more power because they are also replacing the catalyst, which will not pass emissions. I would concentrate on upgrades elsewhere. The benefit isn't really worth the cost here if you wish to remain emissions compliant.
