Got the Indy back today from Indulgence. Put the meter on it and to my horror it is 111dB. Looks like High Frequency noise is bumping it up.
Took the car to Powerspeed and they are making up a 7" Silencer for me and I will get the car back to them on Friday / Saturday to fit it. I decided to go for a new one instead of borrowing one from the many offers of help here as it is transferable to the 4AGE engine (next winter). Thanks to all for the offers.
I got the car back home and set about finishing off some trim. All finished now and as far as I can see only the silencer left so just waiting for the test station to contact me with a date.

Quick aside, while I was at Powerspeed there was a Westie in, Steve Lawson from Croydon, Orange Westie with a Busa, very clean motor, also having a Silencer made. He may pop on here to say hello. We exchanged numbers and hopefully he is a good contact as he works for Toyota, which is good to know.

cheers............... Neil
