Can you tell me at what power does your exhaust manifold becomes a restiction ?
Thanks

Hi Marty,
Its hard to say, as we havent really found it to be a restriction as yet.
We are regularly running 400bhp+ and there is a Leon Racer on our manifold that is running in the region of 550-590bhp, thats with an external waistgate but the casting still flows it.
If you would like to know any more it might be best to give us a ring and speak to Michael, as hes the one that designed it. :D
