...the stock header and the WRX header were identical in every respect except the WRX header has a bung for an O2 sensor on the right (collector) side.
Later I checked out a bunch of dyno tests and found out that the majority of "bag-of-snakes" type headers actually produced less power than stock.
Hey Bill, thank you for that critical info on the exhaust manifold fit. Helps to confirm what I have suspected.
I am keeping my eyes peeled for the turbo exhaust manifold with the up pipe section and intake manifold because I want to have them matched ported to some heads I will eventually have done. I have been collecting part numbers from the dealer for various engines so I can expand my salvage yard search. There is sometimes referenced both a left and right exhaust manifold with different part numbers for the same engine. I thought it was all one piece. What am I missing, do the N/A engines use 2 exhaust manifolds?
You said the "MAJORITY" bag-of-snakes produced less power. Which, if any, produced more please?

Yes you are exactly right the only extra power you will get with the
headers is by port matching, or getting someone to tune the headers
on a dyno.
The standard headers are effiecent just damn heavy.

Hey-N/A motors have 2 exhaust manifolds but the exhaust assembly is one piece up to the 2nd cat. My N/A Borla headers (2nd series) with a custom up & down pipe work extremely well with a 2.25" exhaust. If you`re talking about the MRT or STI turbo headers, I believe they are for upper-end, high-perf. motors (power from 4-8,000 rpm. A street machine may not benefit from these specialty headers but an intelligently designed system FOR THE APPLICATION should work just fine. Some people that`ll be running the 3" exhaust system are going to be miffed because the bottom end (up to 3500 rpm) will be like a WRX--too slow to spool. Except in one situation, larger is`nt always better! Be wise---ROD (AZ.)
