Hi all. I want to buy a performance exhaust, so I decited to go Janspeed route. I wanted decat + intermediate + rear part. But then someone told me that intermediate pipe is waste of money. Is it true? or is there any better exhaust for ZS? I want some bhp gains. thanks for help. Mike

If you are changing the cat and rear pipe it would be silly to not change the intermediate as well.

No m8 change the lot but if you ever change the headers then u will run into probs with emissions so if u r planning that route then go for the sports cat and not the full decat.

emisions in Slovakia are very high because there are many old cars here also without cats. But If you know someone who makes these emisions test than no problem for you. (I know this guy so no problem).
I don´t want to change my headers because of price/bhp gains.(somewhere I read that it give you 8bhp in top rpm.). So if i want to change it it will be better to change it all from headers? if I buy exhaust from janspeed for mk2 saloon is it direct fit? is piper exhaust better in bhp gains?

yep my oem exhaust is rusty especialy rear silencer. I want something with better quality + bhp gains. There is a company making a stainless exhaust but they quoted me 1500euros for full exhaust( really much for that price I can get any brand of known exhaust makers). Is here someone who has own both piper and janspeed? thanks for your posts.

cheapest place i found for janspeed was PTP.

decat for max power and if you still have the 2 pre cats fitted then u may get away with it, not sure what the emissions hav to be in your neck of the woods.

cheers

thanks I will go for decat - but dont know if janspeed or piper, I found that it is 50/50 on here in your cars . Piper has more tailpipes finishes but janspeed sound to me like they are build direct for a mg zs (imo)

Yes. Not massive gains from a catback though, if any. Consensus is that decat is worth doing for gains, I'd say it's worth it for the sound if nothng else .

This was the only one i could find for your model as long as its the 2004+ MKII Saloon not Hatch.

I did however buy mine from Larkspeed though eBay but they don't seem to have any atm =(
