Car Update
Well the new exhaust is on the car. The difference is very noticeable, and the hole in the old box was bigger than I'd thought it was. So the car is now nice and quiet. I also got it cleaned, and redid the tyre pressures. I thought they looked a little low but all the pressures were down around 26-27PSI when they should all be over 30, so they're all now around the 34 mark, much healthier I think.
