Why aren't there OE extractors?

Given the cheap and easy power gains from extractors and exhausts, why don't manufacturers invest a bit more time and money in coming up with decent OE systems? Lots of cars look like the engine design department went flat out to squeeze decent power out of the donk, then sent it down to the exhaust design people whose motto is "Restrict, twist, turn, and choke".

Is there some technical obstacle, as distinct from a financial one? Or do they just reckon the noise would put people off? Be a lot less noisy if they were cast rather than tube, anyway. And cast would last, too.

VK fuel injected 6cyl Commodores had extractors as OE. Old HR X2 Holdens (and GTR XU-1 Toranas) had a two piece cast iron header style exhaust manifold setup. Don't recall any Fords except HOs (maybe GTs as well?) having OE extractors. It's probably a money thing.

EPA regulations on noise and emissions, and cost.

confused

Possibly for ease of fiting on the assembly line? The ones being junked at Tickford had crimps where they are bolted on to the engine to allow for the appropriate tool to put them on easier.

Cast would crack with the extra heat produced from unleaded fuel and I guess the leaner conditions of efi...

Have you checked the head to extractor flange? Some are way off,I would say aligning them up would add heaps of flo.

Usually two reasons, as someone already said, cost and ease of fitment.

Yes, the old "250 2V" engine (XY & XA) ran factory extractors, as did the XY GT-HO Pase III, XA Falcon GT RPO83.

Cost would be the major factor I reckon.

they are easier & quicker to install on the assembly line meaning cars are built faster which means less labour costs etc

So true

The strict standards they have to meet is a joke!!!

Imagine what would happen to after market places if ford actually put out a car with a decent exhaust system!
