Rob,
check out the company below. they've done several parts for me over the years, and have done a much better job than the bigger company's.
They even coated the bumpers, nerf bars and wheels on my 1/4 scale RC sprint cars and it all is beautiful, and no orange peel.
They've done a lot of cobra parts from headers, side pipes, internal & external engine parts,
oil pans to even bellhousing.
Great guys & products.
Look up their site and tell them Kevin Gilmore, with the blue cobra sent ya.
Headers are only $170
Side pipes $300
If the parts are used & dirty, they will sand blast them before re-coating.
