I've tried a number of different methods to quiten side pipes down including..

- Spiralled baffles
- Perforated tube with wrapped exhaust mat
- Manually operated butterfly's
- Cut down cat converters

They all had verying degrees of effect.

I know with the windsor to quieten it down I went to a perforated tube with woven mat which certainly had a good effect. Its still loud but bearable. Prior to doing that it would clear everyone from the pitsheds within a second of starting it.

I think it has lot to do with the proximity of the pipe exiting next to your right/left ear. My F truck had the pipe to rear and was subtle so we cut 6 feet off the length and exited in front of the RHS wheel and it seems much much louder.

Its a tough ask to get it quiet, but tuff and not restrict flow etc etc.

I'm pretty sure my cobras pipes are due for a rewrap as they are starting to get noisy errr again!
