Where to get 2.5" Ramhorn manifolds? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ryan68 · 08-01-2004, 01:45 PM

I need a pair of 2.5" ramhorn exhaust manifolds for a SB. Will these bolt right on my my engine? I'm pretty sure they do, but just have to check. Also, where can I get these for a good price? Where can I get collectors too so I can do my own exhaust? Thanks

Chevy still sells the 2.5 inch Vette manifolds. They have a cast in bracket for the alternator mounting, but that can be ground off easily enough.

Scoggin-Dickey no longer shows them on their site, but I emailed them & they said they are still being produced. Price was ~$120 each.

Mike, if those are truck ones, they will be 2 1/4 inch units. The 2 1/2 are much, much more rare.

Will the Vette rams work? They go straight done instead of curved back like the trucks at the flange. Wont they hit the frame if they go straight down?

Please tell me where you should measure for the 2.5 inch ? At the donut gasket? I would not want to mislead anyone on this board so please reply soon. Thank you, Mike

Checkout www.castheads.com They sell ported rams horns (I did my own), gasket-less collectors, mandrel bent pipe, and a cool 2 into 1 collector that makes more hp than duals (helps to scavenge better). I've got this setup on my Blazer and am very pleased with it.

I can email pictures if anyone is interested.

Aren't the truck ones 2"? Cause when you buy the gaskets, the guy at the parts store usually says is it the 2 1/32"(2") or the 2 17/32"(2 1/2") gasket.

On the fit on the 2½" sometimes the drivers side MM will need to be trimed a little.

I can confirm those sizes-just bought some yesterday-the 2.5 inchers they list for these trucks are for big blocks-stock small block trucks are 2 inches-the 2.5 small block rams horns were corvette only
