Default What would it take to connect a Prodrive axle-back to an RS?

What would need to be done? The old-school RS one doesn't have the right hangers, and the new one you have to "rotate the flange." I have no clue what that means, but would it work if I got the new-school one and hooked it up to a stock wrx mid-pipe?

One of the hangers will have to be bent or relocated. If you put on a wrx midpipe, it will have to be lengthened on the cat side. If I were you, I'd find an aftermarket rs midpipe and rotate the flange on the muffler. That means that the flange will be cut off, then twisted to align with the rs midpipe flange, then welded back on the muffler. Any muffler shop can do this for very cheap.

have an exhaust shop make you a 2.25 inch midpipe, you can have them add a resonator if you like but the prodrive is quiet enough. then they just need to rotate the flange and mount it up. I had it done with my scoobysport.

I thought that 2.5 inches was ideal mid-pipe size for the RS.

Nope, 2.25" The 2.5" has a SLIGHT gain on very high end (5600 rpm+) But it loses a lot of low end torque compared to the 2.25" piping.

why dont you just get the prodrive exhaust for the RS?

that would be much easier.

Because I have a GDA RS, and the hangers aren't the same.

I see.

Any muffler shop can either weld hangers in the correct location on the old school one, or rotate the flange on your midpipe or or on the axle back so it will mate up with your midpipe.
