Ok, guys, let's try tro come to a concensus about the order of the air flow restrictions in our engines.

From reading, here is the list I have come up with (1 is the most restrictive):

1. Intake, specifically the lower intake, but upper and lower usually go together.
2. Mass air meter housing
3. Throttle body
4. Exhaust headers
5. Cylinder heads
6. Cam (not really a "restriction", but changing it allows better air flow)

Let's hear everyone's 2 cents ...

sounds like a good list. Would the exhaust headers include the rest of the exhaust? My o/r h greatly improved airflow

While I wouldn't say that the headers are more than TB and MAF, it's damn near close, if not slightly above, the kinks in each tube is just unsightly.

Exhaust I wouldn't really put on the list if we are talking a mostly stock engine because of course like with a bigger anything (i.e. intake and exhaust) on stock may give you extra horsies but be a drag on low end torque. Of course I guess if we're just stictly talking airflow, then you could say anything dealing with air is better over stock- from the stock restrictive air filter and silencer all the way out the tiny stock tailpipes and catted stock H-pipe. The stock headers aren't to bad on the 94/95s compared to the Fox's but were a little choppy due to the fact header bolt location took presidence over header pipe design.

1. Intake Manifold
2. Throttle Body
3. Crappy cylinder heads
4. Exhaust system
5. Mass air sensor (alot bigger than the 89-93's had)

why is the intake port on the #5 cyl so much smaller then the rest? ever look downyour lower intake at the #5 cyl intk port? you can see almost a 1/4 inch of head. when the intake is off you can see it is smaller then the rest. at least on my gt-40x heads.
