TURBOTRONICS

Hi all I have a 94 wrx import and recently I have noticed my exhaust is blowing from the front especially when cold. When I open the bonnet to try to see where its coming from it sounds like somewhere under the turbo but I carnt see or feel any thing. Im thinking of changing the gaskets but I don’t know which ones to change and what im asking for from the dealer and is there any mods I can do while I have the turbo off and down pipe.
Is there any thing to watch out for when doing this?

it could be the up pipe blowing

can they split or just a gasket

I imagine it could be both,however I think usually it is the gasket. Aftermarket headers I believe are more prone to splitting.

With the engines being a bit noisy it makes it hard to hear where anything is leaking from!!

is it easy to change with some basic mechanic skills and is there any thing to watch out for appart from the studs snapping

only ever changed the downpipe, that was easy enough though. I think there is some stuff you can spray on pipes etc that will detect leaks (gas engineers use it) maybe an idea to try this to locate exactly where the leak is from
