Yer was told after the installation that the gaskets werent exactly made of gold

i'm not being funny but check if your 'y' pipe is still connected to your turbo compressor housing, the dudes that did your tbe might not have tightened it back up properly & it could have popped off at high boost, this happened to may mate last week and it still ran but had rough idle and had no top end, what a relief when we found this!

valid point... however i dont think it is as he said it smelt like exaust fumes..

does it make like a loud exhaust sound under the engine bay or what?

A very loud exhaust sound, very clacky sound, almost stalls every couple of senconds
will check the intercooler piping anyways, cheers,

The manifold between the engine and the turbo is under pressure when boosting. But after the turbo, the is very little pressure in the exhaust system. Those gaskets after the turbo should hold if done up properly.

it aint about pressure mate.. its the heat

The rest of the gaskets should be fine, just the up-pipe and perhaps the down, i mean, if it is the gasket thats the problem, it only took like 3 hours of driving to crack them, then id probably recomend getting different ones for the up and down pipes.

Right, so I should be fine with the gaskets supplied (no up pipe needed)? I'm a bit concerned cause hey, it's only a gasket, I may as well get subaru gaskets.

Who fitted your zort Hybridgx? If you don't mind me saying?

If you want to get a genuine subaru turbo to dump pipe gasket, they are apparently quite affordable. Last I heard I think they are around $30 for that gasket.

I had fats from fatsport fit it for me, did a good price with the up pipe included. If you have an auto, which i doubt many would, its a little tight, a bracket had to be removed to fit it. But other than that, a straight bolt on. very happy with the sound of the system,
