Title: Half Bridge Exhausts
Post by: AshRX on August 14, 2008, 03:32:16 PM
To the half bridge boys, what back boxes are you using? Got tested at 112.9db at 5.5k revs last weekend and I have 3 trackdays within a month and need to quieten it done to 105db max

I did Snetterton on Tuesday and had to stick a turbo blanket up the tailpipe just to get the noise down to 102db

Cheers

I have no idea what Tim used on mine, I have a mid silencer (custom made by pipeworx) and a 3" back box which came off an FD Tim was working on.
