Here is what happens when you dont replace your up pipe.

Davenow · 06-06-2006, 01:24 PM

This is for all the nay sayers out there.
Here is why all you cobb stage 2 guys REALLY should do an up pipe.
Here is why ANY subaru that has a catted up pipe should replace it.

wowsers. Glad I replaced mine.

Davenow · 06-06-2006, 01:28 PM

Yeah, and that can even happen on a bone stock car.
Adding exh and EM ups the chances of this happening tenfold.

MyScoobie28 · 06-06-2006, 01:31 PM

i don't really understand wtf happened?
i see the damage, but i don't understand how it got there or the whole situation. -arthur

The up pipe cat is breaking up, and pieces are flying into the turbo and the exh wheel is destroyed.
That turbo is now junk because the owner cheaped out on the up pipe.

was this on a stg 2 or stock? How many miles?

Dont know the specifics on this one. Its a nasioc guys car, maybe he will see the pics and comment.

But I can tell you this much, I have replaced 7-8 failed up pipes now, and seen at least 5 more. They fail on stock occasionally, 2 were stock, every single one of the others was Em and a turboback. Some failed 10-12k miles, some failed 25k miles, some failed 2k miles. Actually I lie, one was just a reflash.
Thats the bad part, its a gamble, it could last 40k, it could fail tomorrow.
And most failures are worse than that (not like it matters, as that is all it takes to kill the turbo)

cheynex08 · 06-06-2006, 01:46 PM

good awareness post...this should be added to the uppipe FAQ

Davenow · 06-06-2006, 01:48 PM

yeah Ill pm unabomber with the links to the pics

Master2192 · 06-06-2006, 02:13 PM

haha, I'll have to show my g/f this. I told her before I gutted the uppipe that the cat in that pipe is a big flow restriction. And also it could fail and kill the turbo. Turbo's aren't cheap, gutting your Uppipe is

eddie1982 · 06-06-2006, 02:17 PM

thats sucks alot of people are unaware of the risks though

nate49509 · 06-06-2006, 02:30 PM

Looks fine to me.

ghibli99 · 06-06-2006, 02:52 PM

@ Davenow: Thanks for the info, man -- glad I have an '06!

Actually clipped spools worse (but makes more top end)

MF-DIF · 06-06-2006, 03:11 PM

Thats pretty cool. Picture wise.

UM-WRXer · 06-06-2006, 03:52 PM

well good thing td04-13t turbos are a dime a dozen...i sold mine for about 120 bucks. Im sure a replacement isnt going to set him back too bad...and now hes got a nice paper wieght for the desk

semaj · 06-06-2006, 03:57 PM

Does gutting the uppipe prevent this?

sandwi54 · 06-06-2006, 04:01 PM

Thank god I replaced my uppipe too.

indelible · 06-06-2006, 04:04 PM

shouldn't subaru recall all of these cars to fix the problem?

The 06's do not have a pre-turbo anymore. SOA addressed the problem....

For everyone else without an 06, gut the stocker or buy an aftermarket. An aftermarket up was my first power mod

Absolutely. If you gut the up pipe then you don't have any peices of cat to fly up into the turbo. If you gut the up you should pull the egt sensor and replace it with a bolt. All of this is in unabombers uppipe faq.

They would almost certainly face a fair amount of regulatory grief, possibly costing them a lot of dough above and beyond replacing up-pipes. The pre-cat and TGV's qualified the WRX as an LEV when it was first sold. Besides, it doesn't typically happen on a stock vehicle until it is well beyond the warranty.

They'd rather call all these cases "abuse" to stay away from paying for replacing all the up-pipes.

Think of it, $100x every turbocharged Subaru made in the last X years = big money.

Not replacing them under warranty/recalling them: Free.

Which would you prefer as a manufacturer?
