Sports cat has restrictive material in the pipe like a normal cat does all be it reduced. Decat is 100% straight through so decat wins

Depends how loud you want it mate. You need to weight up weather the tiny bit of added performance is worth how f**king loud it is with a decat.

I put my cat back on last month as it was getting annoying on long

Got a de-catted yozza from a yozza with sports cat and it is alot louder when giving it some but i'd say driving normally i.e pottering around town they're fairly similiar.

Both stupidly loud either way :-\

Decat, cheaper, better, louder.

How do you know your cat is "on it's way out" btw?

Its collapsed so its kinda dead already, wont rev freely, but soon as you take the cat out its fine...

de-cat

Man up.

I think that might have just persuaded me ;)

Dont mind loud tbh, i might buy a 2nd hand cat to put on for long journeys though (Providing its cheap)

does a decat on an OE system make much of a difference to noise & performance?

I might be talking pish but as I understand it with the end pipes being so narrow better flow further up the system doesn't really have any effect, noise would be greater but can't see performance being affected (even on a larger system decat has very little effect).

Edit: De-cat inside the cabin
