Headers for mid-engine installation

Does anyone know if there is any company making headers for the LS engines like the 180 degree "bundle of snakes" headers used on the GT40 replicas? I am doing a mid-engine car with an LS engine and would like that type of headers for the sound and possible performance benefits. Thanks

I got a used pair off craigslist that came off a sandrail/dune buggy. The sand rail market might be a good place to start looking for some...

Schoenfeld makes some circle track stuff that may work...

Thanks, I hadn't thought about the sand rail guys. I will do some looking there and see what comes up.

How about checking with the Factory Five guys.. someone with the GTM must be running them and know where to get them ?

The wrap-over geometry of the headers usually makes them end up with primary tube lengths of 40" or more, which will bias the torque curve towards low-end torque production with a corresponding decrease in torque at the upper end.

If that suits the goals for your application then you will enjoy the unique appearance and sound they produce for sure.

The Factory Five GTM builders are mostly running the Kooks system which is not the same. My customer is wanting more the sound they will produce rather than any performance benefits.
