Very interested in Dave Manns observations. Perhaps the exhaust explains the reported superior road tests of RN cars. Makes a bit of a puzzle of the published bhp (although may not be peak).
To summarise, I gather the improvement noted by Dave was due changing from a pipe which telescoped into the silencer to one which telescoped over the silencer, whereas the original would have been same as silencer.
Just to get it all straight can someone please clarify the id of RN original tailpipe, RP original?
Unlike cars with boots, provided not too many rust holes, with a short exhaust little chance of exhaust entering the cabin.
RP pipes can become crushed if the bump stops are defunct.
