200cell Cats, do they really make this much difference?!

had mine fitted, the increase in noise is immense, sounds like I'm ripping open a gateway to hell!! I'm just not confident that everything is right, perhaps they fitted 100cel or they didn't do the connections up and it's blowing? If I go under a tunnel and floor it, it literally hurts my ears it's so loud. Might be being paranoid but I think it's getting louder!

Now I'm not being a Nancy boy, I've had loud cars, one was an RX7 drift car that run a single turbo with a very free flowing back box and a external waste gate. The Aston on full chat is louder!!! Also got the Exige with 200cell cat and a free flowing exhaust, trips the db meter at 99db at three quarter revs on the static test trackside, the Aston is a whole different level!

When I'm just maintaining a constant speed on a level road you can hardly hear anything. And on tickover when you're in the cabin you can't hear the exhaust at all.

I'm planning on taking it to a garage at the next opp just to get them to put it on the ramps and see if they can spot anything obvious. But before I do I thought I'd check on here first to see if it's normal?
