maybe I'm missing something.... but how is FiD in relation to SLS?
Sam @ BMC is a good guy. I bought a lot of flanges from him and his family... there's nothing wrong with having Sam make your flanges. CNC mills are expensive.
I know the guys from SLS when they first started up and bought their Haas. It cost a lot more than they intended and was expensive to pay for.
I don't see why people are trying to hate on each other's manifolds.
Truth of the matter is 99% of the steel used in these manifolds is from China. I know every weld el I've EVER bought was made in china. I buy them from US companies, but they're made in china.
point is... calm down.

Also in refrence to Beissen's power output he's tuned on a Dyno Dynamics w/ no correction factors and those familiar w/ each dyno the Dynamics is one of the lower reading out there. We've had customers out there that have been on both DD and DJ dyno and have had differneces from 12-16%.

Your recent posts in this thread are not appreciated. You should go back and delete all your innuendo. I've had both manifolds in my hand, and they are both stout as can be and both have a lifetime warranty. As for other features, they have their pros and cons. Kinda funny you should mention Oregon Trail - The non-stainless flanges on the ToxicFab are starting to rust in the Portland, OR winter, and it will continue although I'm sure it will never get bad like what happens to non-stainless exhaust pipe underneath a car.
For the person asking the question that unintentially started all this crap, both manifolds performed nearly the same on the dyno. The only clear difference is that the FiD did spool a bit early as they intended with their design. No comments yet on which has better daily drivability because I've been gone the last month and no time to make a proper comparison. Hope to do that in the coming weeks.

damn
seems like I unleashed hell on this thread. Sorry about that wasn`t my intention. Just wanted to gather some additional info before I buy. I didn`t want to post that question on this thread but Mrfred pm box was full and here we go. Anyway both mani`s rock, great write-up
still deciding probably will come down to a coin toss

thanks, but when people say its not as good on a stock turbo thats not true. the first manifold i built went on a camed stock evo 9 turbo car. it was first tuned, then the manifold was swapped and retuned all on a mustang dyno. +26whp and +20tq were the numbers seen after the tune and manifold on same boost. all these manifolds are good in one way or another. all comes down to who the custom buys from.
Also I want to clarify that the FiD Manifolds and products are made in the USA don't know who got the idea that it was not. Its like Collin who get flanges made one place but welds it together when you mass produce anything you don't always have the equipment needed to do so.

A mild steel flange won't expand faster than aluminum like a stainless flange will. A stainless flange has the potential to rip the studs out of the head.

The CTE of 304 SS is closer to the CTE aluminum alloys than carbon steel is. 304 SS does have a higher CTE than carbon steel though, so a 304 SS flange will expand more than the carbon steel studs when it gets hot. The difference will cause roughly 0.002" of differential expansion over an 800 deg C temperature rise. Wouldn't think its enough to worry about.
