How to make my exhaust quieter

[marT350T]

I have a rear engined car with a single silencer in I need to make quiter for this years TOTB.

How can I do this , I have no room to put in another silencer.

Thanks

Had it measured at 0.5m todat but not at 45 deg straight behind the exhaust. measured 121 db at 4500 rpm !

Cannot fit a bigger silencer so the bung I think is my only option.

Are these any thing facncy or jst a peiece in the tailpipe to reduce the bore ?

Thanks for the replies I think I will try and fabricate something.

The car is a mid engined polo with a 1.9 20v turbo motor. (see pic below) The exhaust goes under the bumper from right to left which is mostly one big silencer and then exits at left hand side

I was thinking last night that the reading was taken whilst the car was on the rolling road surely this would make it louder than do a static test , wouldn't it ?

I have a tvr and at a event I got my cars dbs measured and that was 120.8. db I have come to the conclusion that my polo is no where near that. When i get it back i will do a static test and find out for sure
