- Had the front windows tinted to the same shade as the rear. Done at Autoshades in Sutton, highly recommended. I've had 4 cars done there, and they even fitted a neutral look privacy film to the windows at my home - can see out, but from the outside it just looks as if the windows are extra reflective (but not mirror/chrome effect.)
- I took the car into vortex exhausts today - thought I'd get them to have a look at it before I decided for sure to take off the system. Turns out that the pre-cats, cats, silencers and vortex units are all completely burnt out! Only the backboxes are intact. Hence the volume and drone.

Hope I've made the right decision. Cost wise, I think it'll actually work out cheaper than re-fitting a standard exhaust and replacing the knackered cats. Hopefully I'll end up with a functioning aftermarket system, quieter than it is now, with a lifetime guarantee (that now should actually be lifetime!).
Get the car back on Monday.
