noise dilemma
ok so I have done a few mods to the 80 track car and one that is bugging me is the exhaust.
I have kept the manifold standard with the precat but fitted a glass pack silencer (Cherry Bomb) as a decat. I then have kept the standard resonator box and finished off with a Cherry Bomb tail pipe. sound gorgeous and feels like it has released a few horses.
However, a noise test at 1 metre at 45 degrees at 4000 revs shows 96db. If I rev it to 6500 it goes to 108db max reading. Track day approaches with a 105 db limit.
The half revs test is what is employed at Cadwell Park and our Pumesta read 88 db but at Blyton we were warned that we were right on the limit at 105db.
I'm thinking that Blytons test we will fail....how can I get the noise level down?
