from what i gather i might be much better off with a protune and this will help reduce the smell. i was also thinking of having a hi flow cat welded in.

thoughts?
I would not hack up the DP I would get a quality DP with a cat or go back to a stock DP and tune. There is no tune the will improve the catless smell. The only way to stop it would be to seal your cabin from all outside air souces.
