That's the one mine used to be the same as that till I got sport cat and loved it kicked in at 3.5k on the motorway then it was loud but not as loud as it was in my 1.6 escort with only a cat-back lol

Damn, I think I've seen that one. Wouldn't mind a non-res, but really don't want a decat Had one in my old car for a bit, but really don't wanna risk it now, as I'm gonna be declaring all mods (even my K&N is declared.

Just get it an save for sport cat that's what I did

Hmm, now there's an idea

Would that mani fit the ST? :/

Don't think so mate but if it did don't think they would be a gain in power

Forget non branded and get a used Milltek! Honestly you'll thank us for it later!

So Lee is none of that any good for the ST then? I THOUGHT it seemed weird saying it's for the ST AND ZS.

And Dan I AM going to if I can find the parts at the right price anyway. That link is a mix of Piper and Milltek, but as I just said, dunno if it's right for the ST

May be Decat back but I wouldn't say the mani would be it all depends on how different they are to the zs I wouldn't risk it my self for that money you could get a miltek for an st

Aye true. Hmm, I'll just have to be patient.

in that ad he does sat it will all fit the ZS but only the cat back and down pipe will fit the ST.
he also says check the mani, it might fit the ST, but im pretty sure the ZS and ST are totally different

Teah that's what I thought :/
I also was under the impression that the catnack wouldn't fit both though

Seem to remember seeing someone say on here that the cat and cat back are one piece? Is this right? So the catback has to be cut from the cat if you're to change the cat back? I really don't want to have to change the cat as I can't be arsed with the MIL issue.
Surely the back box is separate to the downpipe?

Yeah catback is separate from the cat hence the name meaning from the cat backwards. It's fairly easy to do really but much easier if your changing the cat aswell though as theres no need to cut it just undo the bolts!

Wait, so you DO have to cut them to change the catback? Would this not cause problems with keeping the system tightly together afterwards?
