New inlet manifold??

[Morrisminormo]

Hi
I am am going to buy a large bore exhaust system and a 3 branch manifold. I was looking at my current standard setup and the inlet and exhaust manifold are joined together. Will I have to buy a new inlet manifold? Or can you separate the original?
Has any one had any experience with janspeed big bore exhaust system.
Thanks

You do indeed - but far better is an alloy inlet manifold - as fitted to MG Metro etc. A 3 branch manifold is good - an 'LCB' is a step too far unless the engine is quite highly modified - with a camshaft upgrade.
