Where in the system are the catalysts in the new Type Uk I believe there are three of the pesky performance sapping precious metal items hidden in it. (Not sure if I want to jump straight in and get a full Stainless system)

Andy

 

Centre, downpipe and up pipe I believe.

I'm getting mine removed very quickly once I get my STi

Tim

 

Where exactly is the up-pipe then, I have seen Mr Croney mention he does a replacement one.

Andy

 

Somewhere under the bonnet

I don't know exactly but I do know it's a long job to replace but worth it.

Tim

 

Just before the turbo but just after the headers

 

Tim,
Best to wait IMHO until we see what Prodrive are bringing out for the UK STi before you start to decat your car.
If they do their magic and give you 300bhp+ with a PPP then its going to remove one or two anyway but you may also invalidate your UK warranty by removing the cats now.

I'm getting mine from Europe so not too fussed with the warrenty issue (it didn't stop me on my RB5 anyway)

If Prodrive do bring out a PPP then I'll look into that later.

Tim

 

Going by what they have done with the 01 it would only be a superchip anyway, (although i've got some good figures from it)

I'm sure there will be lots of power upgrades available from other sources

Scott

 

Tim, how much are you paying for the sti from europe? i take it your collecting the car??

Tony

 

Humm, I think you're wrong... The STI VII has only 2 cats : one after the turbo and one central. No more up-pipe cat like in the '01 WRX...

 

What happens when you come to your first MOT with the CATS removed will it fail on emission regulations??

 

Are you sure there is not a cat in the up pipe?

 

i agree im sure there is no cat in the up pipe.
i dont know how many of you have driven them but i was lucky enough to be able to pdi the first privatly registered sti in the uk and i was blown away by it . it pulled well it gripped well and it looks the dogs danglies although i think it looks to high off the ground and it's coming back in to have some morettes fitted soon. should look even better.

 

I still think there are 3 as I saw the pipe that was taken off a Litchfield car at powerstation a couple of weeks ago and counted them. Pretty sure it was from said car as no pipe on it, plus it was next to sti TMIC from same car and very clean. (cats in same places as my01)
Terry

 

Definatly no up pipe cat Dave? who is your source - spill the beans

 

Trust me......

 

Dave I am told there are three cats in the Sti, if not in the up pipe where are they?

 

Well, I have one expert telling me there is NOT a cat in the up pipe, and another telling me there IS!!

Me, i'm going to duck out of this one as I don't know one way or the other, but I shall be straight under the bonnet of the STi's when they arrive!!

 

I've been told there are three by Listers.... 50/50, phone a friend anyone?

 

Listers tell me they dont know!

 

The STi doesn't have a cat in the up pipe.

Amazing that it will pass Euro3 without one, but the WRX won't without a third cat Yet the downpipe and centre cat configuration are the same as the WRX and different to the Japanese spec STi.


Have we been sold the Californian spec WRX?

 

Pete
Which side is your steering wheel on

 

Maybe its the V.V.T thats helping the emission test

 

We looked at two 01 UK spec STI's last week. Neither had cats in the up pipe.

Rich

 

It's ok - both my expert advisers now confirm no up pipe cat

 

Not that I've looked at mine, but the dealer tells me one before and two after the turbo. (Am probably going to remove at least one next week)

Paul

 

3 defo 3! Havent fitted one yet, but I sold a decat pipe to someone in the know who wanted that 21 BHP finding again!

 

The cat before the turbo(up-pipe cat) is only good for emmisions when the engine is cold. Once the engine has reached full operationg temp. It's just a restriction.

Jay

 

Please can sombody with an sti confirm A - the amount of cats and B the location of said cats

 

My mate Jonno has got a jap-sti7, he said there is a cat in the up-pipe and one in the downpipe

I do believe the uk-sti7 has a cat in the downpipe and one in the centre section
