3400 Ported Exhaust Manifolds From MMS (http://www.milzymotorsports.com/miva/merchant.mvc?Screen=PROD&Store_Code=MMS&Product_Code=3x00PEMs)

Has anyone tried these? I know MMS has always had a good record with everyone, so yea. I don't really wanna shell out $400 for Headers. What kinda of power would I get off these, or would I get anywhere near the power I would from S&S Headers..

I think in all honesty headers are the better route to go but sometimes your budget doesn't think so lol. I don't think anyone has really tested the ported mani's to the s&s headers. i could be wrong.

You can only reach so far into the mani to port it. In the end the inner diameter is the same or really close to stock. I wouldn't bother. Save the cash for headers later or something better now.

Waste of money.

Spend another $400, and get S&S and be done with it You'll be much happier ;)

Extrude hone might do something but short of that, I do not consider ported exhaust manifolds to be worthwhile.
