wat differences will i see on a fabia vrs with a high flow cat compared to a decat pipe bar abt £100 thanx

Hi
The decat is without the cat and the sports cat has the cat
On the diesels you do not need the cat to make it pass an MOT , well worth doing
Oh cat is the catalitic converter

sorry if my question was misleading it was the differences in performance gains i was looking for lol

Oooh blimey
Never had them both on the rolling road together
I would say a few bhp but it would be throttle response that would be better , that is with the decat and it is cheaper

I cant speak from experience on a diesel. But I had my RS Focus de catted then fitted a sport cat when the mot came round. TBH I could not tell any difference in throttle response and only dropped 2bhp.
I fitted the Milltek turbo back system with sports cat. The car boosts from low down and I have never had any problems with it. A few people have reported that after fitting a decat. Their turbo boost spiked and caused the car to go into limp mode.
I think the main difference is in the noise. The exhaust will be noisier with out a cat fitted.
