Thanks for the link, nanard289. Fortunately, I have a mate who’s a brilliant welder and guess as a last resort I could get an assortment of bends from the States. But it seems ludicrous living in a so called industrial nation such as the UK it should be necessary to ship from the States simple things like pipe bends. Talking to a mate in the States a while ago about just this subject, he was amazed we had so few facilities for fabricating exhaust systems. He reckoned in the States every other exhaust shop had the equipment. To prove the point, a few weeks later he had his local exhaust centre make a new system for his Mustang powered Volvo – time taken 3 hrs - cost less than $400!!
