I bought an 02 sti uk spec from a dealer, the car had been remapped with a decat downpipe on it by JGM. The dealer before they sold me the car removed the decat downpipe and replaced it with a standard part.

Can i run the car safely without the decat downpipe without wrecking the engine. I don't really want to have to buy a decat pipe as the car seem quick enough and appear to run alright, but what do i know.

Please explain the possible problems and if i need to buy a decat pipe. If so are the one's on ebay for £125 any good?

Cheers.

 

So make them pay for the re-map.....

They took it off, now it's your problem.

dunx

 

where are you?

I'll check it with detcans and laptop etc as is if you like

If I put another decat downpipe on will that put the car back up to it's remapped power of 339bhp. That's the power it was putting out after the remap.

I thought the car would have worked ok but just at a reduced output.

 

Please someone answer my question.

 

differing makes etc.. but should be closer than the standard one.

It may well be safer but it is more restrictive and was mapped with a less restrictive exhaust which will effect fuelling and boost and ignition the engine will take etc..
agree it is the right direction rather than fitting a decat if it were mapped with cat etc

since it was mapped with a decat downpipe fitted the logical thing to do is fit another decat pipe and hope it retores it back to the 339bhp.

Cheers.

 

agreed.. but if you want to do more than hope drop me an email and I'll check when I am as near to you as I can be and we can meet up and I'll check is FOC.
