Finally finished fitting the 4-1 manifold after 3 evenings. It gave me a chance to investigate the rattling from the exhaust silencer and it does indeed seem like the cat is breaking up. Seems like a good excuse for a carbon silencer soon! Save the current silencer for MOT time I think. Anyway, onto fitting the new manifold. With the exhaust system stripped off and weighed because I'm a bit anal (new manifold saves 620g you know), it was time to attack the bodywork once again. I really hate that job. I started off making the hole square, then slowly expanding it towards the front of the car, checking if I could feed the manifold through each time. For those interested, and please don't use these as your starting dimensions, I ended up with a hole around 165mm wide, 120mm tall and 235mm from the front of the tub. Looks like there is still some filing required on that hole! It fits quite well, and I did a better job of the silencer this time making sure it wasn't pulling down on the support bobbin. The only thing I'm questioning with myself is if I should grind these welds down a bit. I think I'll leave it. I'm not chasing every last bhp and it's brand new so doesn't really deserve meddling with! First impressions are good. I've only had it idling for 10 seconds or so but it already sounds deeper, less raspy. When summer decides to arrive I'll take it for a decent drive.

They are tillett B5s They have the edges on but need to be trimmed ever so slightly. This car has a Type 9 tunnel. MT75 may be a but too wide on passenger side. B5's are best if you are a 'well built' driver otherwise B6's are fine.

I will be coming via St Mary's to Selkirk, so can give a sitrep then. See you there, Dave.

We are still on everyone.Its to late to cancel now with the BBQ etc ,When we meet at Selkirk with the border 7's we can maybe look at the route I've been informed the St Mary's loch rd is rough as a badger's and there will be lots off standing water. See you all later Lizzie Bryce at 9AM

Back O/T, there's a good reason why the line of sight for those mobile phone aerials shown in the first post is about 8-10 mles, but the reception range is only 2-3 mles - lack of transmitting power. All the towers transmit short range to each other because that's the limitation of their power, which is why you see so many towers and why mobile phone calls are expensive. People freak out about microwave power without understanding how microwaves work. If you overrode the door interlock on your microwave oven at home, left the door open and set the microwave oven to full power, it would harmless to you unless you got inside six inches of the open door aperture. Microwave transmitters are no different.
