Turbo up pipe

[Bill]

Hi all I have heard several stories about turbo up pipes (the one's with cat in ) if I change mine to an sti version, as I have a 2004 wrx.do I need to get a remap straight away or will the car run ok ?

The car will run fine but you won't see any benefit. Also, you will get the check engine light on as the catted pipe has a temp sensor. A little resistor in the plug will remove it or a mapper can remove the error.

I will have to get a full system and a remap then as I'm looking for a nice improvement in performance

Well if ya do need a resistor I got a few

Sorry to thread hijack, but I've got a cat back at the moment, if you get turbo back/decat will you fail MOTs?

Almost certainly unless you have a tame mot tester or maybe a sports cat

That's what I thought, just wanted to make sure. 👍🏻

Sports cat not guaranteed to pass, (speaking from experience)

Yeah did hear that stants, I hear maybe that you can go rag the **** off it and bring it back hot and you have a better chance, but then we are probably back to the tame mot tester again

It's all good mate, have ways and means 😉 just more of a heads up to anyone that may be thinking of buying one to be able to sail through,

A 200cel sports cat should pass emissions
