Need an exhaust manifold for my crossflow. The one I have is a matched 4-2-1 performance one but unfortunatly its off an 'essie and will not fit. What are my best options?

1: I assume as its been through many many heat cycles I cannot straighten it - anyone have any experience/suggestions?

2: Am building a Ginetta where standard fit is a Zetec. Its top chassis rails will fowl a LSIS type exhaust - more suit a Fury I suspect, with something like a horizontal exit for 2feet'ish before downsweep. Anybody know where I can get an 'off the shelf' solution?

3: Get one purpose made - a little concerned on price as don't want to shell out too much ('stainless' or 'one-off' until have proven the engine isn't knackered - can anybody suggest good manifold manufacturer and approx prices.

4: No welding skills - so can't mention option 4!!

tar very much in advance,
Andy
