So, the one thing my R8 was missing, was the V8 sound.
After a bit of research into the available options, I decided to go for something unique.
Since I have decided to mostly keep the R8 stock(ish) and get a project car to play around with, I opted for a custom system which could look stock.
So, I too a trip to Advanced Automotive Systems in Newcastle. http://www.aas-exhausts.co.uk/
Stuart and the guys there, really know their stuff, and if you are considering a custom system for your Zed, give them a shout.
Its a switchable system, with a switch in the cabin which opens/closes the cutouts.
Vid is taken with an iphone, so not the best quality, but you get the idea.
Video is a warm start, with the cut-outs open. They close 1/3 way through vid, then open again for the last 15 secs or so.
As always, comments/criticisms welcome.
