Default 4 inch downpipe for ramhorn manifold

does anyone make, or is it even possible, a 4 inch down pipe for the ramhorn style manifolds.

Just got a top mount kit for a car and i am kinda jealous of the 4" pipe...lol

Any idea where to get a stainless short cone? The only converters ive seen for sale are long.

Thank you.

UGHT OHHH!!!! looks like for under 200 bux i could make a stainless 4" DP minus the steel converter.....HMMMMM

What do you think would be the power gain going from a 3 to 4 on a sc61 ported s housing?

The car dyno'd 483 on a 2.5 inch downpipe on pump. I just made a 3" about a week ago for it, changed to equal length mani, 70mm TB w/ ported Victor-X mani...hopeing to get some better numbers this year, like over 600 on race gas.
