Charlie @ Pro Speed comes thoroughly recommended by me!
I had an exhaust made by Charlie in August last year following recommendations from various people and I was not disappointed.
He will make the exhaust to your spec, so you can choose exactly how you want it to sound and look. I went for the 3.5" slash cut tips with what Charlie calls a 'mid-sport' tone. The slash cut tips fill the recesses and align with the rear bumper perfectly. It almost looks OEM.
As for the sound, if you're pottering around town, it's no louder than the standard exhaust, but when you put your foot down it has a nice sporty note without being too intrusive.
If you go with Pro Speed, you won't be disappointed.
Let me know when you're heading over... I might be around to say 'hi' (and I might even be in my Trophy by then!)i am planning a trip there this year, aiming july/aug
