When I had my BC fitted someone told me an old member, Adrian? Had one fitted with decats and it was insanely loud but also got some of the best dyno results too
Are you sure they are going to let you track the car if it is too loud
Just checked it again and vpower is 143.9 near me. So, that works out at £117 per week just on fuel.
Why not use Tesco or Sainsbury Super fair bit cheaper and then at least then you will get points.....
I prefer the stock ride height myself it also means you can actually drive it wherever you want too
Get some metal polish on that exhaust does look like a Scorpion...
For £600 you could probably get some 2nd hand leather ones
Or you could get some made up maybe
Those would be my options anyway as a good excuse to upgrade or change...
