Be aware when I did a test fit yesterday, my new DB killer whistled like a flock of canaries were following Monty down the road.
The other one that I lost at Castle Combe was identical in design, but didn't do this, however it was adjusted to be quieter so that was probably why it did'nt whistle?
I just thought I'd make you aware, anyway I've removed it now as it's my Surrey Rolling Road power run session tomorrow morning.
