No bother. I went ahead and fitted it anyway. On first start up I thought I was after making a massive mistake but it settles down quickly and, as you say, has a beautiful V8 roar to it. It's a massive improvement.
I'm surprised by the lack of drone and how quiet it is at cruising speed but how vicious the sound gets when you are on it. It's not quiet at all when giving it the beans but not really any dronier than the stock exhaust when cruising. The car gets noticed a lot more now alright which for me is a good thing. It was too anonymous before.
It also feels significantly faster than before with the remap. Great modification. Engine mounts were well worth doing too.
