purchased car de-catted?
Hello all,
I am purchasing a "new to me" 2002 sti prodrive style. The dealer who i am purchasing it from told me that they had to replace the cats, discovered during the mot that the previous owner had removed the cats.
My question is: since the cats were removed i can hopefully assume the previous owner got it mapped. if this was the case the dealer putting cats back on would not hurt things, correct?
follow up: would it be a problem to put those de-catted pipes back on after i take receipt of the vehicle?
Info on driving and looking it over: the car appeared to have standard backbox and started fine and ran beautifully, no knocking or exhaust pops to speak of.

If it were mapped to run de-cat it would need mapping again if the cats were re-fitted. It would be ok if you were only fitting the cats to drive to the MOT and back "off boost" but if you were intending on keeping the cats fitted it would need a map tweak.

is there a way to tell if it was mapped for no cats? for instance shouldn't there be popping on deceleration if it were not mapped for no cats since there were less restriction on the exhaust.
