Thanks for the compliments, the more I drive it the more I just want more of the sound. People have contacted me asking for more info saying they actually prefer it to the higher pitched frantic scream of the Ferrari style V8's. I would say mine sounds more like a Maser GT than a Mustang or other detroit metal, it's a nice angry sound.
My car has removed centre cat and straight through (no rear silencers), it does not affect emissions (cannot 100% say for sure but it didn't on my last MOT).
Here is a little video I did after we hit some small underpasses yesterday, kids love it too
