Fortunately thanks to Peter and Anthony at SBITS the car's now back in action and I no longer have to drive a Vauxhall combo hire van to work (hire place was out of cars that weekend 
).All I can say is WOW.
After 3 weeks of driving a hire van it really drove home to me just how fast our cars really are. Made me fall in love with the tubby all over again 
Can't say that I will be using iridium plugs in my tubby again though.
The offending plug was less than 15K miles old and had never been re-gapped. It's not the first time an iridium plug tip has separated on my car either, although unfortunately it was the first time I didn't get away without damaging something. When we looked at the pistons later Peter pointed out the plug tip shaped dent in the piston but otherwise there weren't any signs of detonation on the pistons.Thankfully I managed to hide the repair bill away from my wife
So anyway I thought I'd share a few pictures of what I had done while my tubby was over at SBITS.
You'll have to excuse me for not washing the car prior to the photos, lol.Customised titanium exhaust:
This exhaust originally came with quite bit of piping
- some of it was titanium and some of it was stainless. We ended up losing most of this original pipework in order to make the exhaust fit over the subframe so only the initial bit of pipework after the back box is titanium and the rest is stainless. Weight wise the back box is approx. 2kg and the new stainless B-pipe should be around 3+kg which puts the total exhaust weight probably somewhere between 5 to 6kg which is a good 7kg or so lighter than my old Mongoose and about 14kg lighter than the original stock exhaust.It's a little on the noisy side for me at the moment so I have ordered a bung for it and also bought lockys96's Burns stainless silencer for attaching later
