Re: 454 exhaust systems
What do you want to know?
Merc put Gil manifolds on a lot of 454s, they work very well. Stainless Marine makes a nice replacment. GLM makes an aluminum copy of the Merc manifold, it's a little cheaper and lighter than the Merc. You won't see much increase in speed just from a manifold change. But, as part of a perforamnce package(cam, carb, intake and exhaust), you can really wake up a 454 mag.

You can find the revolution exhaust on ebay, usually go for about 50 bucks less than what you can get them on their website, polished set is a little more money.... look nice for the money...
