Hi Grant

My vibration comes in about 2700 rpm, mostly due to the exhaust note on
deceleration. My current solution is to add another hanger after the
muffler. As is, the main hanger is welded to the pipe just after the cat
and before the muffler. This bracket is attached to the block. That left
the muffler and tailpipe freely suspended. It's weight alone from
flexing causes vibration. My setup is similar to to WBX, cat and muffler
inline at the back, where I believe yours has the cat off to the side, a
bend to the muffler as in the Eurospec photos. I am not sure what type
of hanging system you have.
As for the noise, as I wrote I have not done anything yet, only noticed
that when I had stuff, (boxes, wood etc)over the new lid, it was like
the former noise level in the WBX. I plan on insulating the deck lid at
sometime. The type of muffler you use will also determine the noise
level. Originally I had an exhaust manifold with one outlet which was
quieter and less vibration, but the 2 into 1 downpipe dramatically
increased my torque, but it is a bit louder and more vibration to deal
with. Hope this helps.
