Thumper has now been fitted with G56 exhausts and a Spitfire air intake. Kwik Fit probably wouldn't have fitted the pipes much quicker. The delivery was at 1200 and the engine was running by 1330: to be fair, the upholstery had all been removed ready for the pipes to arrive. I had given the joint on the old pipes a squirt of WD40 the night before and they came off easily. In the meantime, whilst all the upholstery was removed, my CXO cleaned and balmed all the leather.
Thumper certainly made the front door rattle when it first kicked off! Seems to be getting smoother as it runs some more (do ECUs program themselves to changed conditions?). The improvement in performance is outstanding. The car was always pretty impressive, but it now really is on song but not as noisy as the KH stage 1 car I tested a year ago.
The size of the chambers and guard is obviously bigger, but I am already used to it. Slightly less room in the garage though, although they are a fraction shorter and easier to step around at the distal end.
