brilliant result ! keep the clamps loose line the headers up to the ports then line the collector box bolt hole up at the rear , a screwdriver or thin bar helps to line the bolt hole up before you try to put the bolt in , can be a bit fiddly to do !when its all lined up tighten the header flange bolts then the lower clamps , then fit the silencers .all the nuts and bolts are at 20 newton metres.
