Exhausts

Back last summer I managed to get some 2nd hand exhausts which were in good condition and perfect for my headers. The questions was what to do with the steel headers to stop them rusting. I looked into ceramic coating, but it's rather expensive, and doesn't help reduce the under-bonnet heat, so I opted for exhaust wrap. The problem with wrap is that it can absorb moisture when the car is left and that will rust the pipes. So, a coating of very high exhaust paint (actually I used fireplace paint!) solved the rusting problem and the exhaust wrap will reduce the heat. All good after a very wet winter with only a few engine starts... The wet winter has caused a clutch problem though - more on this later :-(

Once the headers were wrapped and fit, cutting holes in the body was simple and looked great once the plated were attached:
Once the exhaust L section was clamped on to the headers, adding the side pipes was easy with a couple of bolt holes into the chassis and some new rubber bobbins. I have also some exhaust filler to keep the noise down for IVA, but I'll stuff that into the exhaust just before the test so it has maximum effect.


I couldn't wait to fire up the v8 beast now that the exhaust was attached. Sadly it coughed and spluttered and there was finally a bang and burst of flame from the air filter. I quickly turned it off and waited for my pulse to return to normal. After some thinking and forum advice, I checked the timing, since there was fuel, and clearly spark. It was way out! I set it to 10deg BTDC and boom! It fired up and made a great noise. After a little while it even ticked over fairly well. I then got a boast of confidence and felt like I could rule the world. So I slid it into gear and reversed slowly a few feet.....YES! It moved. Sadly after a few feet the clutch pedal went to the floor and the car jerked backwards and thankfully stalled. The clutch stopped working. if you read on, this became the bane of my life for the next 8 months :-(
