Default midpipe question

is GC midpipe same as GDA?
ie if you take a WRX midpipe, will it mate?

I was under the assumption that it didn't. But who knows.

I don't believe it's just a bolt up, I think a flange is clocked to a different angle. If you can get one for free, it might be worth while to have an exhaust shop make if fit, $50-75.

for sure the muffler end is clocked the wrong way. The other end is probably much worse. Turbo vs non-turbo. I doubt that it is close at all.

For the record... a stock WRX exhaust is 2.25".... so it would thereotically give you better flow. I believe the flange that is clocked wrong is the end that meets the muffler section.

Here are some comparison photos:


The pipes seem to follow the same basic shape (WRX top, RS bottom; notice the cats in the WRX pipe).


The muffler end is clocked slightly different (WRX on right, RS on left, hangers clocked to same position for comparison)


The cat end is clocked significantly differently. (WRX on left, RS on right; hangers clocked to same position for comparison)


The WRX pipe is slightly shorter in overall length (WRX on top, RS on bottom).


The WRX pipe is 2.25" in diameter.
