These classic ram pipes are designed to maximise air flow potential from the HS4 and H4 1.5-inch SU carburettor, as used on all historic race engines.

We keep two lengths in stock, 1.5-inch and 2.5-inch, which can be selected from the menu above. The shorter length tends to work best on high RPM applications, whereas the longer type can give an improved mid-range performance. Of course, all engines have different requirements, so it's not a case of one-size-fits-all.

Please note - these are a traditional cast aluminium component and some imperfections can occur in the finish.
