Sound proofing!

[Jamo]

Backbox to Longlife:

"Thou shalt have no other box before me"

And they're a faithful bunch... Steve, didn't Longlife skip the centre box in your car as well? I'm sure putting one in would really help... could get one put in if/when you get the downpipe done, it crossed my mind, but wouldn't that add a fair bit of restriction? Guess I'll keep waking the neighbours up on an early morning start... if they're that concerned, they'll fit double glazing.

Boxes only add restriction if they use restriction type of sound damping.

You can have reflection or absorption sound damping

Exhausts

Perhaps I'm being optimistic but I've found that new exhausts can quieten considerably after a period of time. A good coating of combustion products maybe does it. I suppose Longlife would tell you how long to wait before there will be no further reduction.
