Brett,

I am making my side pipes at the moment. They will be 4.5"OD with 2.5" perf pipe inside with 3" collector and exit.

These are copy of Mikes. Thanks Mike.

I think you will need this OD if you stand any chance of getting noise down to acceptable limits.

I should have them completed in about a week if you want to view them.

Regards,

Phil
