Attempt to redirect exhaust noise

As I previously wrote my noise levels are now down to 94-96 dbA on the intake side and 101 dbA on the exhaust side.

In an attempt to reduce the latter I did a quick test to fit a 90° steel tube and point the exhaust towards the ground and see if it made any difference.

The result was a bit unexpected. The exhaust noise went down an half dbA, but the intake noise raised to 98 dbA.

I've been complaining about this before, but noise metering appears to be quite random.
