How loud is the tapping from the valve train ?

Can´t say I have ever noticed it. A bit more induction roar maybe, but that´s not a bad thing in my book

Back to back, carbon and alloy plenums, carbon is slightly noisier.

Seems normal once you are used to it.

Having the JE plenum mines not noisy but I also have roller rockers so it does make it quite.
Daz have you had the ACT manifolds coated ? Did mine it does keeps the heat down in the cabin I thought it was a gimmick.
