Did you only take the cats out from the boxes ? Or you cut the exhaust pipe before and after the cats boxes and then welded a new pipe between?
Taking the cats out of the boxes and leaving the boxes on the car seriously affects the power of the car, negative way.

Yes the boxes are still on the car, so I guess they have just been taken out. Performance is still good though

I asked a friend who works in Sales at the main Bristol Audi dealer to check the price and if they are still available. Audi stopped production of s2 cats in Dec 2012 and even back then they were £800 EACH!

I now have a pair of used cats to put on the car and the retest is tomorrow.. fingers crossed!
