Another GM MAFT thread Options

[KOU In3]

Ok, I'll be upfront that I'm just being a bit of a Devil's Advocate here. I like the MAFT and from what I hear, I'll probably end up owning one. I've plowed through most of the DSMtalk threads on it too. But, just to cause trouble I'll ask the following from those of you that have it.

Anyone have any concrete dyno numbers or even track numbers and actual gains from this mod? Before and after improvements?

I know the 3.5 in flows like the Mississipi in and of itself but when you neck down to the throttle body is all that flow lost and even disturbed by all the steps to get it to mate up? The 2G MAS looks to be pretty close to a 3" MAS flowing more or less straight through.

Although tuneable, can it match the increments of the SAFC in terms of fine tuning?

Granted, everyone who's bought one seems to love it. I'm just wondering if anyone's truly dialed it in on the Dyno and done a side by side with the 'old' SAFC 2G mas combo.

OK, flame suit is on. Time to endure the punishment of the translators.

I've actually had the chance to run both types of 02 eliminator pipes. Other than noise you won't find much of a difference. Diverting the exhaust back into the pipe should disrupt the flow, but at this point the exhaust is probably still getting most of its velocity from the properties of thermal expansion.
