opensourcepirate A difference of 4 inches sounds like they ordered parts for the regular 2005 instead of the California emissions 2005. The CA one has an extra catalytic converter so the mid pipe attaches a few inches further back.

elborak We just took my son's 2005 Outback to a local independent garage for A/C, brake and exhaust work. A/C & brakes were fine, but they picked up 2 different midpipes and neither one would fit: both were "about 4 inches too long". They said they may have to order from Subaru but preferred not to due to the cost (this being a 14 year old car). They welded the worst hole and left the rest until we can get this figured out.

After we left, I did note on cars101 that Subaru changed engines starting with 2006, so the 2005 is the only Gen 3 with that engine. I'm wondering if the various independent parts catalogs just lump all of 2005-2009 together even though there's a different fit due to the engine change.

Anybody know for sure?

Edit: This being an '05, I suppose it could also be federal vs. Cali emissions.

WantAnOutback I don't know why but nearly every non stock exhaust piece I buy does not fit.

scoopburt That's a shame. I have the Bosal pipe and it fit properly and had 3000 miles on it no problems

opensourcepirate Update:

I got the Bosal midpipe in the mail. It actually ended up fitting - mostly. It's definitely a little bit shorter than the old pipe, but I was barely able to get the mufflers attached. It's leaking from a bad weld where the resonator and the pipe meet though.

I ordered the real Subaru part from a online store run but a dealership one state over. They e-mailed me today to say that the part is actually too big for them to ship out, so I just re-ordered the part for pickup from a local dealership.

opensourcepirate That's probably a bit far up for me, although I do have friends in the area. I'll keep you in mind if I'm planning a trip.

opensourcepirate Thanks WantAnOutback,

I ordered Bosal 286-557 from Amazon before I saw your post. Amazon says it's returnable if it doesn't fit.

I might try it out if it fits. Otherwise I'm pretty sure that 4200AG09B is the part I'm looking for. 4200AG10B seems to be for the Legacy Outback Wagon, like you were saying.

I might be interested in picked up that part in Vermont. How far up the state are you? I'd be coming from a bit west of Boston.

WantAnOutback The Bosal pipe is not good. Even if it fits, the resonator will develop a rattle very quickly and drive you nuts. I have ordered that PN twice and neither fit without welding modifications.

From Subaru: They are different part numbers for california and federal emissions for the mid pipe. They may be slightly diffterent lengths.

Further to u5 vs federal, my guess is the reason for 2 part numbers for U5 "w and w/o" outback is that 2005 there was a Legacy Wagon and an Legacy Outback Wagon. the legacy (non outback) exhaust may hang lower since it has rear exit mufflers????

The FEDERAL part for bosal is BOSAL 286975. I happen to have one sitting here, will try to figure out what the difference is between BOSAL 286975 and 287557.

I also have a Bosal 287-557 with the Resonator removed and with the muffler flanges cut off. Yours for the taking (in VT) if you want to convert to a single muffler setup.

mprosco91 That pipe you're looking for has nothing to do with emissions. Never mind CA or federal. Only thing that matters for California emissions is the cat mainly and any other emissions equipment.

Now unless being CA emissions makes the cat physically bigger, there shouldn't be any difference in the two pipes besides being for a sedan or a wagon.

Get the one for Legacy Wagon. It's the same thing. Or do like someone else said and go on Rockauto or something. Itll be cheaper.
