Rear bumper exhaust cutouts

[Fitzy]

I apprehensively modified my 65 GP rear bumper to accommodate the new larger pipes that will eventually be installed. The result looks great (I reckon it should have left the factory like that) but I'm keen to know if the GTOs or any other model from that vintage have a similar factory setup. I want mine to look as 'factory' as possible, so using a GTO or similar as a template will help.

Here's a pic...

The 1970-1972 GTOs had their dual exhausts exit the rear valance panel. Dual exhaust on the same year Tempest/T-37 or Lemans (the GTO's sister platform A-body cars) would exit behind the rear tires.

Nice. That looks great. I guess I'll stick to what I now have. Once the apertures are filled with chrome tips, no-one will ever know that I hacked that bumper with an angle grinder.
