Making a new Hillman Imp race exhaust mainifold

South Africa has always had a vast amount of motor sport tallent,not only in driving,thats an F1 world championship I might add (Jody Sheckter,Ferrari) but the engineering people who make the cars and engines to make the sport possible.



The Hillman Imp full race exhaust jig,which means all exhausts are the same principal dimemensions.They can be supplied without the inlet manifold as well,we have now exported them to five countries.

With the sellection of various bends required to make the fabrication,they are complicated and
not an easy job to make,each tube is hand shaped using heat and sand inside the pipe to stop
the tube collapsing,pipes are end tapered to get them into the CNC flange plate too.



This is the easy part,the inlet flanges are the hard part,as the trumpets are not only very
short but are bent and tapered as well.

The finished job (exported) and made in 2006.


Richard Tomkins,an Imp Club member on a second visit to Cape Town with one of our manifolds in 2009,also exported,thats the manifold,not Richard.

Made to order,they do take some while to make,so if your in the market for one,ask sooner rather than later.
