In late 2006 my passion for Porsche that had been kindled by owning a boxster lead me to search for a 911. In February 2007 I found a lovely, well used 964 carrera 2 coupe in GP white and embarked on a new adventure. This running report is about my 964 that would be used for high days, holidays and track days and be a 'project car'. It wouldn't matter if it spent time waiting for things to be fixed as it wouldn't be used as a daily driver.

Got the exhaust repaired (Jun 09)

I'm pleased to report that the exhaust issue has now been remedied. The boys at Unit 11 Warrington got a new flange fabricated which is a few mm thicker than the old one. This allowed them to saw off the old flange and weld on the new so that the same spacing was retained (important to ensure that the cat could be bolted on without stressing the exhaust system). A complete new heat exchanger for that side would have cost £2,000 (and a good used one up to half that). The all in cost from Unit 11 to make and fit the new flange was a tenth of that! Here's the old flange now separated from the car:
The flange was initially tacked on to the outlet of the heat exchanger:
Then the inside was welded to make it gas tight:
