My H&S exhaust is now ready and will be installed on Friday 11 November. I'm looking forward to the drive home, but possibly not the 2h drive there in the morning!
For those who are interested, the Goodyear F1 Asymmetric 6 are tremendously grippy and quieter than PS4 with less road roar. One step towards a quieter car. Next will be the Hayward & Scott exhaust.
