Does anyone have any info or experience with an aftermarket exhaust for the Tribeca? I am picking up a 2006 Black limited on Monday,to go along with my recently purchased Forester XS Premium. Already thinking about upgrades , K&N air filter is in the mail. Proud to be a new member of the Subaru gang!

There is nothing out there for it. I think since it didn't hit the JDM market hurt us. Although, the Aussies are known for their Subie high performance parts. Maybe they might make something for it when the 08 comes out.

Does anyone know if the y-pipe on the Tribeca is the same as on the Legacy? If so, the legacygt aftermarket axlebacks bolt right up to the y-pipes of the n/a engines. The exhaust system on the 'beca looked pretty similar to the one on the Legacy, so maybe that's an idea???

I want to say someone already tried the Y-pipe and it did not work. They ended up returning the exhaust. Search around on here or NASIOC.

Good thread. I was also just wondering how close in size the dual outlet exhaust of a legacy would be to the tribeca.
I'd love to have a little bit louder exhaust note. Perhaps with an axel back.
anyone have any under shots of a tribeca?

OK, it's official. Legacy exhausts DO NOT fit on the Tribeca. I tried to fit a set of LGT Prodrive axlebacks on the 'beca this weekend, and the DO NOT FIT. The y-pipe is different between the LGT, 2.5i Legacy and the 3.0 Outback. The reason is that the y-pipe on the 'beca has to clear the spare tire which is mounted under the car.

With some custom pipe work they would fit, but that's more than I wanted to do at this point.

However, I did get my 5th tire mounted on the BBS's, and confirmed that a full-sized spare will fit under the car, albeit while sacrificing some clearance.

Nice. How much clearance are we talking about? Are those BBS's 8" deep rims like the factory ones?

good post on the mufflers thanks for trying.
I would also love to see a picture of the legacy exhaust mated up to the tribeca to see how much custom fab is required.

I'd love to throw a set of mufflers on our Tribeca but seeing as how it's not really 'my' car I'm not aloud lol.
Magnaflow makes some really nice stainless mufflers with tips already on for a factory finish.
Locally at least we have a few places such as Kooks Custom headers that would do a full stainless exhaust for it....but again it's not my decision to make.

I've also never heard a H6 with mufflers...don't know how good it would sound. :confused:

COBB made an exhaust for the tribeca but it was a one-off deal for a sema car. they actually did the hedders back. Why don't we try a group buy of some sort to see if Cobb would reproduce just the axel back for us? any takers? just a thought.

Hey guys, I was the one that orriginaly tried the Legacy GT exhaust. As mentioned before it doesn't fit. Nothing about it is the same. the mid-pip, Y pipe and even the mufflers are differant. You could just do mufflers but for our cars the big restriction is the Y pipe.

snork

01-29-2008, 04:55 AM

Yeah, the Y is usually the main restriction point on most OEM exhausts. The mufflers are a pontially easy/cheap custom swap, but all you'll really be doing is changing the exhaust sound.

The youtube video says it's an Outback XT, which would be a 2.5L turbo 4, not an H6. Didn't sound bad though.

03-26-2008, 10:33 AM

Anybody tried the HogZaust on the Tribeca? Over on LegacyGT.com, Hogmeat started a trend of putting a couple of washers on the Y-pipe flange bolts. On the 2.5 turbo, it sounds pretty good - adds a nice throaty burble to the sound. It apparently doesn't sound as good on the non-turbo 2.5, but it may sound nice on the B9's 3.0.

The only cost is a couple bucks for 8 washers - two for each bolt, and the minimal time investment. It's an easily reversible mod. Anybody up for trying it?

snork

03-26-2008, 11:51 AM

I don't get how putting some washers at a flange point would change the sound? Would you purposely be adding some "leaks" to the system b/c there are no gaskets between the washers?

SubieDriver

03-26-2008, 12:31 PM

Yep, you got it. Built-in exhaust leak. On the 2.5 turbo it sounds surprisingly nice. Not sure on the 3.0 non-turbo.

I am thinking of having a friend who has a shop to create a true dual exhaust from the headers back through some HKS or Trust Exhaust, I would love to get a complete Ti kit, when I compared my wifes G35 I would only need to fab a short piece to make it complete fit. Not sure if it will be wide enough to wrap around the spare tire.....ugghhh..... Does the Legacy exhaust come close, and are there any true dual exhausts for thatwhich are not custom??

Morning all

I have a custom fitted exhaust on my 07 B9. Previous owner did this. Made by Powerflow (www.powerflowexhausts.com) I see that the have an affiliation with http://www.louscustomexhaust.com in the US.

It is a wonderfull howl that turns into an outright squeal past the 6000 rpm mark. Also - according to the mechanic that was involved (I contacted him), when Dynotuning they got about 25 KW extra on the wheels! This was really special according to him - hence him remembering the B9 - lot of potential latent in the H6 3.0. Apparently they took out the Catalytic converter? This sounds strange to me? Maybe Peaty will know - he seems to be an authority on Subi's

Prior to speaking to the mechaninc, I could never understand all the comments about the car being sluggish (and ugly for that matter). Especially since we live at about 6000 feet altitude and it is generally accepted that normally aspirated engines lose about 15 - 18% of their power up here.

I am driving her down to the coast tomorrow, and so we'll se how she goes at sea level. For now, the car screams past 165 in 3rd without breaking a sweat. It is fast (in my book anyway) on acceleration. Off the line not so much as 2 tonnes is a bit!

That does sound pretty remarkable that they measured +25kW at the wheels...that's 33.5 HP! Most cat-back exhausts usually only net 5-10HP, the factory cats must be pretty restrictive and adding high-flow cats usually only adds another 2-5HP or so.

Removing the catalytic converter is a big no-no here in the US. No way you can pass inspection unless you got a buddy at a garage.

AFAIK, the only way to get a non-oem exhaust is to custom fab one.

The LGT one may be close, but you lose the spare tire.

Bringin' this one back again. I'm sure others have done it too but here's our TriVecta with a 2.5" custom exhaust to Magnaflow mufflers. We may add a 2.5" cat back as well. Kept the stock tips for a clean look. Sounds pretty good now though...

No...just a smooth low deep rumble at idle, then a great smooth tone through the RPM's that quiets down when you lift the throttle. Sounds super good when you drop to manual mode and downshift coming down hills (we're in the Mt's). The H6 def. has a smoother rumble to it compared to my 4 cylinder turbo that has that choppy boxer sound we're all accustomed to. Over all I give it :tup: :tup:

I'll post a sound clip soon in my other thread...

Hmmm...may have to argue with you a bit there...not ricer at all for the sound, just the look. BTW that vid is no H6, just a solid boxer 4...low rumble..good sound. Not a fan of the muffler and tip but still sounds like a suby.

The 08' 09' Tribecas (H6) still have the suby sound, just much smoother than the 4 cylinder boxer motor. I've just emphasized it and deepened the tone by going with 2.5" piping and mufflers. :D

I've seen reduced low end power when going with a more free flowing exhaust.

Never lost any of the low end torque or power...especially since the exhaust was free'd up a bit more. When I say intake, all I've done is remove the intake silencer (sound) and added a Perrin Panel Filter. Sure the motor breathes a bit easier, but the filter is mainly for filtration due to our dusty dry environment. I do believe there are gains overall, but mostly I'm shooting for a little more sound as my wife felt the Beca was a little too cush!

jrm

08-17-2009, 03:42 PM

they only went with a cat back on that. Granted it was coupled with a supercharger, intake and ECU flash.

To me this begs the question. If you did a cat back and a intake theres got to be some improvement wouldnt you think. A ecu flash could add to the improvement.

Thinking of a 2.5" catback w/ the magnaflow mufflers and using the OE tips. What model magnaflow mufflers did you use? And when you routed the 2.5" tubing back did you go under or over the rear axle? I cant remember if the OE exhaust goes over or under the rear axle.

Freeing up the intake is pretty simple. I did the intake silencer delete and added a Perrin foam Filter for flow. Coupled with my custom cat back (http://www.sb9t.com/forums/showthread.php?t=1062), the butt dyno told me things were flowing much more freely and sounded great. Dont think the highflow cat will make too much more of a sound difference, just the mufflers you go with will make a diff. Others have actually gone cold air or ss tubing to replace the plastic intake and ducting to the throttle body. Do a quick search and you'll find these. C

im proud to say that me and a buddy custom fabbed a cold air intake with the help of Cobb tuning. there is hope in making a really pretty custom cold air intake. what i did was i took aluminum pipe (3inch) and just used a couple 90 degree and 45 degree bends, mocked up the amount of straight pipe i needed, cut it, welded it, did some grinding, and painted it satin black to go with the black plastic cover under the hood. Cobb Tuning makes a Short ram intake for Mazdaspeed3's (which my buddy has) which have the same mount for the MAF. Fortunatly he upgraded to the cold air, so i took his MAF mount and filter, and now i have that sitting way down by the fog light. im a little skeptical about driving in downpour rain now, but im happy with the sound. it looks amazing and professional, now im ready to swap out my stock cats with Magnaflow High flows, custom fab some Exhaust into 2 Magnaflow Mufflers at the end. i dont want too much noise, but i want that power! ill let you all know how it comes out.

This is the sound I think I am looking for. Lowest frequency idle, not really raspy. I certainly dont like the tinny sound that a traditional ricer makes at high RPM. The post says no cats (I will have to leave mine on for emissions) and magnaflows. I know there are a bunch of different magnaflow series. Anyone have any ideas on which ones produce the lower tones not the high pitched ones>?
