Need to remove the downpipe on my 53 plate sti and replace with a decat down pipe

Just wanted to know if its a straight forward job or is it a nightmare as a friend is doing the job for me

Advice needed

Cheers
Andy

 

shouldnt be to bad on a car of that age mate,rusty bolts is the main concern but if you give them a good soak in wd40 or the like first and leave to soak then its usually a straight forward job

 

easier to take the intercooler off to do , then the turbo shield remove that.
then
3 nuts , and two nuts and bolts . on the turbo
small bolt on gearbox
another underneath , then two nuts and bolts that join to center section ,
oh yeah and o2 sensor to swap .

they not bad to do
rich

 

Hope it comes off that easy lol

Thanks for advice, mate doing the job for me reckons its a bitch of a job he has been told!!

 

Dead easy mate,get the engine warm 1st as the bolts will come off much easier,and should not snap,I changed the original downpipe last week on a 1995 classic and no such problems even with rusted bolts,some wd40 sorted them out.

 

lamda threads stripped in mine when i done it and they arent cheap on an 06 sti

 

I've just done mine. As said above, WD40 & a little bit of leverage & it's quite an easy job to be fair.

 

i've just done mine whilst changing the turbo,

it's not too bad to just do the down pipe part from all the bloody heat shields, they are a real pain as you can't see all the 10mm bolts that have stupidly long threads for some reason

 

I know there is a lambda sensor in the cat underneath the car as that cat has been replaced and the lambda sensor is bolted into that.

Has the down pipe got a lambda sensor in it as the downpipe i have bought hasnt got a thread in it to bolt a lambda into!!!

JUst trying to find out as much info as i can as my mate is doing the job for me lol

 

mine is an 03 uk sti and my friends is a 04 uk sti and we don't have a lambda in the down pipe near the turbo my other friend has a 03 jap sti twin scroll and he has one in the down pipe near the turbo and one further back

 

Mine is a 53 plate uk one, middle cat has already been replaced, and i cant see a lambda sensor by the turbo!! just wondering if it was hidden somewhere where i cant see it lol.

Hope pipe comes out easy!!!!

 

down pipe now fitted, just waiting for duncan to remap it tomorrow now lol !!!!

CANT WAIT

 

Remap now done thanks to Duncan, again he has worked his magic, very happy with car. O and the LAUNCH CONROL works a treat hahahahahahaha

Thanks Duncan you are a star

 

My pleasure Andrew

I knew it wouldnt take you long to try the launch control

 

Yeah its a dream, just span the wheels in the wet lol but in the dry it just grips and ***** off like **** lol hahahahaha

Thanks again
