Very impressive duo you have there, well done!

Good call on the Dundon, had it since day one on mine too. Fantastic product, if I bit loud if you go all out (race headers etc... angel). Did they take out the particulate filter on yours then? 

The OPF is part of the headers, so when I installed the Dundon system, the OPF was removed automatically.  I’m running street headers with cat and their new electronic valve loud muffler for the Speedster. 

 

Our North American cars don't have the particular filtersSmiley, it's just a shell isn't it?
