OK folks, ESR exhaust now fitted.
Here's my write up -
1 - Jack up car and secure on axle stands
2 - Take one look at the job, grab the yellow pages and ring round some fitter
3 - Pay a local garage for an hours labour and enjoy, cut free but wallet slightly lighter!!
I bottled it! Got the car up on the jack, had a go at the bolts on the backbox and realised when I was searching for a blowtorch that this was beyond me. Took an hours labour at a local exhaust/tyre place (Law's Tyres for anyone local).
The owner said of the exhaust - What a piece of kit, not sure if I should fit it or play god save the queen on it.
The guys fitting it were well impressed, one slight issue they thought the midpipe should maybe be slightly more angled as it currently rests on the a beam under the car, but there appears to be no stress on either part, no wobble or rattle so looks good.
I've got a few pics during the installation but waiting till the sealant has properly set before I go ragging it but first impressions are great. Its loud if you bury that right foot but at idle and just constant speed you'd hardly know it was there. I've still got the baffles on but they'll be off later on.
