Cheap eBay sport cats... how bad are they?
Discussion
So I need some replacement downpipes and cats.
Comparing the prices of generic ebay stuff (most of which looks like Direnza), I'm looking at maybe 25-30% of the price compared with the mainstream Milltek, Scorpion etc.
Just how bad are the sports cats on these cheap ebay deals? Being non-typed isn't a problem.
Give me your horror stories before I buy some

My own experience of aftermarket cats was with a Pug 306.
The original cat had a split in one of the pipes & it was quicker to stick a cheapie aftermarket on to get it through the MoT.
12 months later it failed badly on emissions.
By this time I had welded the pipe up on the original cat.
Refitted the original cat & sailed through the Mot with very low emissions.
Chat with the tester - who I've known for years - he said this is not unusual, the cheapies are often OK for one test but not for subsequent ones.
The original was more than twice the size of the cheapie.

And more than twice the price too 
OE cats are designed to last a lifetime, aftermarket ones not. Some of the old ones we take off now and again on EOLVs are worth a fair bit too due to the contents, I got about £80 for a good one the other week, the aftermarket ones aren't worth much.
When it comes to environmental issues people ALWAYS point the finger elsewhere and make excuses, never at themselves.
The fact is doing something positive begins at home.
Diesels are so much cleaner these days until some d
head removes all the emissions equipment and gives it an overfuelling remap.
I distinctly remember as a kid walking along the main road and have trucks belch out black acrid fumes all over me, you don't get that anymore.
Anyone who removes emissions control devices from a road car is an imbecile.

Unless the manufac blags the emissions test in the first place...The fact is doing something positive begins at home.

It really pisses me off following cars/vans in a cloud of black diesel smoke. Should be harsh penalties for it in my book.
