as above but a few questions i wanna ask:
1. both pipes have a threaded hole in the sides...whats these for and do they need blocking off
2. there is a slight bend in the pipe between the flexi and the cat, is this supposed to be there?
3. have 2 springs/coils....what they for
4. the pre cat and sports cat flanges dont 'perfectly' line up, are they suppose to or will they bond tight once the bolts are in?
5. i have an adaptor ring by looks of things for connecting to my standard centre section, does this just seat inside the cat and the centre sit onto it?
sorry if it sounds dumb to some, but i dont know the answers so
