Maniflow freeflow rather than a conventional lcb. Slightly more torque and no silly y piece. On the advice of maniflow I once ran one of them with a maniflow rcm system, toad version rather than race, and the performance was superb, and sound beautiful - not loud but but throaty. The rcm system is only £99 at the moment which is a bargain. Personally I'd look no further than that. http://www.maniflow....58&product=1363

See this link for details of the rcm. http://www.maniflow....ew=page&page=52

looks like there is a maniflow stage one on it. just had a proper look underneath..

do you think stage 2 might be in order given my engine spec?

No unless you want to give me your old perfectly adequate stuff. If that is the case then yes absolutely

There isn't such a thing as a stage 2 exhaust. Stage 1 is a decent inlet and exhaust manifold, better exhaust, air filter and carb needle to suit. The next step is a decent well flowed head and then uprated camshaft etc.

There are no stage 2 exhausts. The LCB manifold can be described correctly as a Group 2 manifold as it was homologation under the FIA Group 2 regulations in around 1964 for the Cooper S.

Happydude, you should be a happy dude with that set up. Personally I'm not sure you need the 1.5 rockers but otherwise a decent rolling road tune would be what I'd do, see what it's putting out and take it form there.

"Roller rockers" not "rolling". 😀
