https://www.infinity-exhausts.co.uk/ did mine and they are not that far from you, Its a nice blub blub blub noise when you let your foot off and a nice low American V8 type noise at low revs and some throttle then after about 3k revs the noise sounds like......... Hmmmm cant think of a way to describe it, I guess If pushed i'd say the engine is singing kinda like a F1 car and I'm not sure why it sounds so good but it could be because its 2 exhausts and not 2 into 1 or maybe the sport cats but when you are up to speed and cruising there is no booming or nasty noises at all and at part throttle its almost silent, and no I don't work for them

but they will make it how you want them to and you choose tailpipes at no extra cost though I made him cut the ones I wanted about because I'm a difficult sod, the only downside is its in the sticks and there is nothing much to do while you wait
