Since I put my sooper-dooper custom stainless exhaust on, the drone, boom, resonance - call it what you will - especially around 2 - 3K RPM or when the engine is labouring a bit (uphill 5th for example) is too noisy for comfort. I had en extra box put in at the front, which helped, and as it settles down it is getting quieter but still not enough for a comfortable ride (my most common trip is an 80-miler to the coast, and it is not a pleasure after half-way)
So..I am thinking about applying some acoustic matting to tray and soak up the excess sound. I have bought a quantity of self-adhesive "Deadmat" which is guaranteed to be the best in the universe bar none. Question is - what actually produces the "boom"? Is it the panels vibrating is sympathy with the exhaust? Where should I use the matting to best effect? I don't want to just stick it willy-nilly on every metal surface, 'cos if any repair work is needed (IF?? who am I trying to kid??) it may be a crapper of a job to get back off again.
Any ideas?
