Nothing will fit from previous generations - Subaru went for a dual exhaust for even 2.5i models for the 2008+ Impreza and Forester, and those were the closest fit for the 2010 Legacy models. Previous generation vehicles are not even close, you'd spend more fabricating them to fit than you would having a system fabricated from scratch.

 

Given the costs involved and the gains possible (Lots, and Not Much), you are probably better off having just a muffler installed.

just hoping someone makes one

 

Doubtful, not in a derogatory manner, but b/c the demand from the owners doesn't merit the R&D. Honestly you can have one made for less. Find a muffler you like and have it welded in place of your stock muffler. :)

I took some measurements with a micrometer.

The size changes as you go back, here are some measurements I took.

Keep in mind the pipes are not perfectly round so i tried to get an average at different points.

 

All measurements are OD

60.5mm or 2.38" after last cat, before center muffler

54mm or 2.125" after center muffler

50.1mm or 1.97" inlet to resonator

55.4 or 2.181" out of resonator

 

What I have in mind is replacing the center muffler with a 2.25" (304SS) straight pipe, I figure it will fit into the front pipe, then over the rear.

If it doesn't sound right I can swap in a magnaflow.

 

I understand the GT's and 3.6's dual exhaust system will accept 08+ WRX axle backs, so here's hoping one of the aftermarket suppliers will start selling just the left side if it fits ours as well.

I can see there is a precut exhaust exit on the bumper it self. In one post a guy

Used the modified turbo manifold to generate the rumble sound but I believed no

Performance gain.

 

I emailed xxleration and borla but they confirmed they haven't made one for 2012 yet. But they do have for 2010.

 

 

you would have to do some cutting of the rear bumper to fit a duel tip.

it would be nice if there is a nice catback performance for 2.5i .. dual tips probably ...

AVO makes this system just for our measly 2.5i :lol:

We have a cutout that is easily removed. You may have to get a hanger welded on.

 

 

when he said duel tip i thought he was saying a duel tip muffler, not a duel exhaust. yes there is a cut out and most 2.5i's dont have the passenger side hangers
