EA82 don't have exhaust manifolds??

EA-82 (and i'm pretty sure all others) use a header pipe setup, or "y" pipe. So... no, they don't have "exhaust manifolds." The exhaust ports DO converge at the head.
Just be careful and use plenty of WD-40 when you take them off... Steel bolts in an aluminum head + lots of heat usually = big headache. An impact wrench can be very helpful here too. Just be VERY careful when you go to put it back on that it is torqued properly (do not try to get that "extra half turn" out of it).

I've never done headwork on a Subie, but it is apparent to me that the intake valves are at opposite ends of the engine, and the exhaust valves are in between them. In other words, the front cylinders (1 and 2) have the intakes in front of the exhausts, and the rear cylinders (3 and 4) have the exhausts in front of the intakes...
I love learning this stuff

The car is definitely quieter, a tiny bit more torquey, and get this... it's running cooler :eh:
