Stock Exhaust Manifolds
Hi,,,The Mission Here is stock appearance,,,so no headers at all..
the question is there anything you can do with these boat anchors too make them flow a bit better or does anyone know of stock appearance aftermarket ones...
Thanks Rail

Re: Stock Exhaust Manifolds
Not to my knowledge. The design of the "boat anchors" really hurt the exhaust flow, and I don't believe they make aftermarket ones that flow more, just stock replacements

Re: Stock Exhaust Manifolds
I think it is the L98 manifolds flow better than the L03s....I'm sure porting & extrude-honing them couldn't hurt.

Re: Stock Exhaust Manifolds
Oh yeah.....
Think about using Corvette aluminum L98 heads, painted black, to keep the stock look. Unless you are getting aftermarket aluminum heads.
Either way, paint them black to hide them.
