Everything I've read suggests that this exhaust should be reasonably quiet at motorway speeds (70 - 80). 
Mines very loud / boomy at this speed but gets noticeably quieter at 95 - 105.
My car still has the original cat fitted though the emissions light is on. I guess this is because the mount between the manifold and cat had failed when I bought the car and I needed to have a new mount fitted. I guess water or something may have got in and damaged the cat?
MPG seems fine (averaging about 32).
I guess there's something wrong with it but ideally I'd like a lift in another car with one fitted to confirm this.
