hey thier
i have a 1310 engine with a big cam, i was just wondering on what people would recommend on the extractors that i should get ?

For a road car, a Maniflow medium bore LCB is hard to beat.
Play with exhaust pipe diameters from LCB back though, optimum size depends on the engine.
My 1412 with RE13 cam likes a 1-7/8 pipe, my 1360 with its bigger RE282 cam and head likes a 2" one.

I use Janspeed, (mandrel bent and well made) - 13/4 pipe into a 2 inch straight through muffler.

Whatever you use, I would recommend (if you have a rod change gearbox) putting on a lower engine steady bar, as often you can end up breaking exhaust brackets or the top of the centre branch of the extractors.

You can get a set of chinese maniflow copies for between 180-200'ish.

Quite nicely made and sound pretty good as well. I had these on my last car and thought they were awesome for the price. The head fittings are cast in steel and already ported to the max, unlike the perrys. The welds are cleaned up inside and the joints include steel clamps to stop the leaks. Outlet pipe diameter is a healthy 1 3/4
