Hi all,

Looking into getting the KAM racing decat manifold.

Seen a few post where people have said they think decat'ing' will result in limp mode on a gti?

has anyone had experience with decating their gti and wether they go into limp mode?

cheers

If the O2 (or lambda) sensor is upstream of a cat and there's no downstream one, you can mod any car without a problem. Until mot time. The emissions test will pick up on excess hydrocarbons and carbon monoxide. But some engine ecus are so good that you'll pass without a cat. But not many..... a few mercs, the odd porsche or bentley. Definitely no ferraris or fiats. They're awful without cats!

mine should be better this year as it has sat with the sump off for a bit, been cleaned out and been serviced.

it's empty now so I'm wondering if using the premium (all the time) has in some way had a negative effect on it, I might do this one on regular and see what happens.

Means your engine is in excellent condition! And all sensors are bang on the money. :)

good to hear.
