I've been under the car a couple of times, at first I found there was a small air leak between the middle pipe and back box joint which I covered up with a bit of exhaust bandage. I initially thought it was still blowing through this but I've since been under the car again and it's air tight.

I'm hoping the weather is fine over the weekend so I can get the car on some ramps and have a good look at it, I've felt all the way round the new exhaust and can't feel any holes anywhere, and as I said in my first post it's getting really annoying, if I wanted my car to sound like a boy racers I would of bought a big bore sports exhaust system.

Just seems really strange that it's blowing apart from when I'm turning right. Which is leading me to think it is in fact resting on the heat shield of similar, and gravity is pulling it away when I'm cornering.
