CVH EFI exhaust Ford Orion

I have a Janspeed tubular manifold for sale complete with heat wrap. It goes as far as the standard joint just behind the gearbox.




PM me if interested.

Smiler.

Pm sent. And are they? alot of things I have been looking up have been efi/mfi I thought they were the same fitment...

I wouldnt mind a full janspeed exhaust, just finding them is a bit curse word! should unleash a few horses, I have read that janspeed usually do give a 5% gain on power, just going to do the usual exhaust and airfilter mods before I start spending some propper dosh on the car.

The manifold, as stated, is going to improve things more as other engine mods are incorporated. It will basically provide the foundation to allow other modifications to have greater effect by reducing the restrictions and compromise of the original cast iron manifold.

The manifold is made from mild steel as are most contemporary performance manifolds for this engine. Stainless manifolds can be prone to cracking due to the stresses involved in heat expansion acting in various directions on the various routed pipes. All bends are mandrel formed to prevent narrowing of the pipes at the bends.

As for volume, yes the Janspeed system is loud, but that's the exhaust system, not the manifold. You should be able to bolt up a standard exhaust system to this manifold and retain normal noise levels. Of course the overall performance effect could well be diminished depending on what other modifications have been carried out to the engine.

Even if you decide not to go for my manifold, this is definitely a step in the right direction. Fitting a 'sporty' exhaust system to a standard manifold would be a bit pointless as the exhaust gasses have already been restricted at there source.

I might look into options for fitting a tubular manifold to the Escorts Zetec.
