Fingers crossed someone has the inlet dimensions so I don't have to take mine off.
How would that work Peter? Is it a slip inside baffle at the beginning of the one into three pipe, or a slip in to each of the three polished exhausts?
How much difference do they make to your exhausts in note?
The D&Ds need to go from 'American obnoxious loud' (standing by to be flamed by my US friends

) to deep throat triple classy loud (UK Bond style).
Fantastic offer Peter.
