Exhaust fab
I saw this 2day at the Newark Auto Jumble....
It's done by Classic Custom Fabrications based in Newark. www.classiccustomfabrications.co.uk Nice demo piece but if it was on my car I'd want the exhaust pipes the same length, but nice quality of welding just the same. They will also sell you stainless steel mandrel bends and perforated tube also so you can build your own.

Oh man, I think I just made a stain on my chair . I would ordinarily agree about pipes being the same length but if you look closely 1 & 3 are linked as are 2 & 4 which makes me wonder if this is done deliberately for pulse tuning?

As with all things to do with engine tuning no two opinions are the same but every body says they are correct. Given that you have just lost 200-300kg worth of car to build a roadster looking at the bigger picture does it matter that the exhaust manifold design has lost you 3-5 hp but cost £300 plus to look pretty?

Exhaust tuning is a black art especially in two strokes and one bend wrong here and there will lose you power.
£300 would be cheap for a cutom exhaust,AAS in newcastle do them and if you have too ask the cost you probably cant afford it and they are always booked for months ahead.

The last paragraph of the exhaust chapter of the "Performance tuning in theory and practice, Four strokes" by A. Graham Bell:
