[DeTomaso] Removing ANSA resonator tips?

[May, Andy]

I'll chip in here since I think Mike was originally enquiring on my behalf - I was initially looking for a way to remove the baffles in the exit tips to get an indication of the restriction (if any) they provided. My intent was not to destroy anything in the process, but to be able to simply insert or remove them depending on whether I was racing or on the street. I felt my car was already plenty loud enough for the street and attracts about as much attention as I want it to from those of a law enforcement persuasion.  I have since found out that my car (a late Euro GT5-S) has GP3 exhausts and mufflers - this is the way it came from the factory - and so the tips are not going to make any additional restriction to the flow.  The can has a perforated Y tube from the inlet straight to the tips - this is why it's already plenty loud!

My intention now is to make up a set of straight-through pipes from the headers so I can replace the complete system and do some back-to-back testing on the drag strip. This way I can determine if any worthwhile real-world advantage could be realised by investment in exhaust changes/modifications. I don't plan on doing this before next spring as there are probably only a few weeks of weather left here in which I can enjoy the car before it will be put away for the winter.
