Hey Mark
Really sorry that you are disappointed with the Sport system you purchased second hand.
I recognise that the exhaust system is not to your liking - your clearly looking for something quite loud...
Our Sport (Non Powervalve) system has been designed specifically with a target market in mind, that is to say a system which gives a great sports tone on the move without setting off alarms or more to the point droning in the car.
I think to say "I was at least hoping it would be a bit louder than stock" is unfair and in our opinion wide of the mark, something that the many owners on here would bear out.
We offer a wide number of variations in our range (greater than any other brand) in an attempt to try and appeal to as wide a field of owners as possible - every one has been thoughtfully designed and thoroughly tested. Even the Prestige system which is our most stealthy system gives an upgrade over the stock exhaust sound.
When you have driven the car perhaps you might want to reconsider your statement, as potential owners may find it mis leading.
Thanks
