I unfortunately find myself in the market for a turbo up pipe.

Any *thoughts* on the available after market offerings (eg: Cobb, BPM, Perrin)?

 

And as a related item:

Anybody have any for sale (before I dig deep and buy)?

I actually have just looked for one for my legacy, as the stock one had a crack. I tried the APS unit, and had issues with fitment.

 

During my search, I heard that the perrin is pretty good unit, and not too expensive. I have also been looking at stock STi up-pipes as they don't have a cat in them.

The up pipe is the pipe in the whole system that runs the hottest.

The Perrin pipe is well engineered, but lacks an expansion joint, maybe I'm wrong, but either it will crack, or the lower exhaust manifold will crack, as something in this situation has to be able to "give".

The BPM is identical to the other, well, I'm not going to say "el-cheapo" pipes out there, but it is at the lower end of the cost scale, and they have taken the trouble to place the expansion joint away from the bend, so it should flow ok. I bought a BPM crossover pipe and have no complaints about that product.

The Cobb up pipe is a completely different animal, is in a different price range, and too has no expansion joint. It is a cast pipe, and probably will work the best, but I worry about cracking, specifically that expensive, hard to find used, exhaust manifold.

I had not *thought* to try Subaru (for an STI pipe). I tried Subaru for a crossover pipe, and at $400, I went elsewhere. I'll go and see them tomorrow.

Ok.......update:

Stock pipe: 44104AA010 $305.96

STI pipe: 44614AA000 $496.65

 

These are the best prices I can wiggle out of my local Subaru dealer.

 

Side by side:

they are for all intents and purposes identical. Same diameter piping, same style heat shields, same flanges, no cat.

 

STi Up-pipe has a big "P" printed on it.

STi Up-pipe has a slightly different heat sheild mounting braket (Same bolt spacing though) than the Leg Turbo.

STI Up-pipe heat sheilds are welded in more spots

both pipes have different part numbers

Ok.......update:

Stock pipe: 44104AA010 $305.96

STI pipe: 44614AA000 $496.65

Those are some expensive extra welds!

Ahhhhhhhh.......... it's ok, I have been told:

Once the supply of 44104AA010 runs out that the part number will update to the 44614AA000 number.

 

ALL Subaru 2.0/2.2/2.5 turbo pipes fit in the same spots, no matter the year, the only exception is the up pipe found in the WRX models with the TD04, whose bolt pattern is a small bit different.

 

Never mind the welds, aftermarket "go-fast" stuff is running 50% of OEM, and I am quoting "best Canadian wholesale price" (the dealer is paying less).

Your stock U/P does not have a catalyst in it, correct?

Right, no catalyst.

That's good to know the sti & turbo leg up-pipe is identical. I am trying to get my hands on an sti up-pipe to make the comparison. But it sounds like they're the same. I'd still prefer an sti one, simply because it's newer then the used turbo leg's running around.

I wonder whether the Baja U/P is also the same? The reports are that the Baja has a catalyst in the U/P, though I've never looked...
