ZS exhaust questions

[Muncle Trogg]

Whilst running through some pre-MOT checks I noticed that the back box is blowing a bit from a split at the bracket. Not sure if it can be bodged so on the hunt for a new back box for a 120 but have a couple of questions.

First up, is the one fitted at present a standard box:







If it is would anyone know the part number so I can try and track one down.

Second question is whether a 180 back box would fit? My gut instinct is that the bore is going to be different but have seen a lot more second hand performance boxes on Ebay for the 180 than the 120.

My guess would be that you've got a standard box.

The standard 180 rear box has twin outlets and a noise reduction mechanism, that should be connected to the inlet vacuum. This added complexity is probably what makes the standard exhaust more expensive that an after market stainless on.

IIRC, the bore on the 180 exhaust is big, 2" or -2.5" or so.

Thanks for the info. This is a 120, hence wondering if it was standard fit on a 1.8L engine.

Have now managed to source a full Powerflow system, including decat, which I'm hoping will fit with no problems. All things well should be on for this weekends SS.
