Hi,

Could you help with the outer dimension measurement of the 4" Disc's and End Cap...

I know this sounds odd, but I am going to mount the SuperTrapp 4" setup on a 4" OD Round Canister and just want to make sure that the OD of the 4" Disc's and End Cap is compatible...yes there is plenty of area to drill and tap for the SuperTrapp 4" Disc's Setup...

This will be installed on a Polaris RZR that has LTE Dual Exhaust on it...we want to tone it down and still be tunable instead of the stock Quiet Core that is untunable...

Thanks,
Cole
