Pretty sure it doesn't as it's the 120 not 180 model. So do you think a tb & induction kit will give more power than an exhaust? I suppose it would actually. But neither of those things are shiny hun... :frown:
The 180s are KV6 and iirc have a totally different TB set up? but its a later model and i was under the impression all MK2s have a 52mm TB? will have to ask ninja_182 (i'e just text him)....
as for power, the ZS doesn't have allot of power gain from an enclosed cone like the F has because it's not as badly a designed system (it gets cold air from the wing so its not like the F sucking from the engine bay) but an enclosed cone wouldn't be anywhere near as restrictive... there's also allot of them around second hand (remember it can be off a ZR/BRM/etc as well makes no difference) hence why there ten a penny
as for the exhaust not a huge amount of power there either unless you replace the whole exhaust like my mate martind1 has just done with his ZR
this is because the ZS has a more complex system, its not like the F where its:
Manifold
Flexi
Cat
Backbox
its more like
manifold
down-pipe (with pre-cat)
flexi-pipe
a connector pipe
cat
a connector pipe
mid-box
a connector pipe
back-box
the restrictive areas are the manifold with pre cat.... the main cat (obv)... the mid box (a sort of pre silencer) and the back-box itself
you could spend a couple of hundred quid on a back-box and get next to no power and not much better sound (as 90% of the system will still be mild steel not stainless which is how you get a pure tone)
your much better off saving for a little while, getting an induction kit for now (just for that grin factor grunt when you nail it if nothing else lol) and waiting untill you can afford a full stainless exhaust from someone like powerflow (where Sav-MG another good friend of mine got one for his ZS from) or Longlife where martind1 got his ZR system
If Stevie were a F or TF i'd say spend the dosh on an exhaust backbox every time but a ZS is a ZS not a F/TF and there a bit different
of course as a stop gap you could have your mid-box taken out for around £40 and replaced with a stainless pipe (powerflow do this, UK-Biker yet another Teesside meet regular had this done and it makes a surprising difference, more torque in the mid range and a sweeter tone, mind you his is a ZS180 so might not be quite the same)
oh little disclaimer kara im no ZS expert, i've serviced and worked on Sav-MGs but most of my knowledge is because Ninja_182, Sav-MG and ukBiker are teesside meet regulars and good mates and what info i have i've gleamed from them and trips to powerflow with them etc etc
but im pretty sure on everything i've wrote and defiantly recommend a full stainless system when you go for an exhaust as its much better value for money (you may spent £400.00 but lets face it just a backbox for a F is £300 and Longlife and Powerflow both come with long guarantees, and if you sell the ZS you can allways put the old system back on and sell separately
