You should still wrap it.

This is generally the recognised way of doing it so that the overlapping exhaust pulses will not interfere with one another to create undue or uneven back pressure. The idea being to strive for for equal cylinder to cylinder exhaust flow so as to minimise cylinder to cylinder differences from residual gases.

Frost do a UHT manifold paint that can be used on heat wrap for all you engine tarts out there.

That looks very nice. :thumleft:

What are you doing with the old system (and what is it)?

If you are selling it I may be interested because I suspect my manifold may be cracked (need to check) :(


Hi mate, i have been told by david the last owner that he has been told by anna (the owner before him) that it is a Magnex exhaust system, and looking at it i think it is...

i may keep the old system as i might not like the sound the new manifold and middle section will give. but most likly i will keep it just incase when i do sell the car i think it will sell faster if it was all oringal or atleast with the oringnal manifold. as i tend to keep anyparts which i modifiy.. but i wil let you know mate.

i know i wont need the middle section if i leave the new manifold on...

Yes it is a Magnex fitted on GUB and to be honest with you I think you are making the right decision keeping it...

I am not even sure my manifold is cracked, all I do know is that it's either leaking from the head gasket (which I replaced a short while ago so I doubt it ) or the manifold is cracked. It's not leaking from anywhere else, that I have proved. If it is cracked I can fit an NA manifold and drill and tap for a Lambda sensor. :thumleft:

I have a spare manifold with lamda sensor hole off my US car, I believe they are the same. Feel free to come collect it :thumleft:
