Yes, that's a bit of a negative to these units - the sharp increase in pipe section upsets the gas flow creating a little bit of restriction.teK-- wrote:Check out how big the pipe diameter is compared to stock:

I now have a couple of areas inside the dash which buzz/rattle whenever I'm cruising at a constant speed. It doesn't happen when idle or when flooring it. I think it's a resonance causing something small inside the dash to move around.

I do however get a rattle from the back of the centre brake light vibrating against the rear windscreen when the car is cold, cause it holds the revs higher, it vibrates a little more. But it only happens for about 20seconds before it warms up enough and the revs drop.
