Alrighty, as I promised, here are the pictures.
Here is the driver's side exhaust section, without the Ti tip:
I measured the internal long-ways diameter of the oval on the exhaust section:
As well as the distance from the end of the oval to the end of the exhaust (7.74mm):
This is a somewhat rough measurement of the entire length of the larger diameter exhaust section, before it necks down:
Inner diameter of the Ti tip mounting hole:
And last but not least, total length of the stainless steel bolt:
If you need any more measurements, let me know. I repeated each measurement a few times to make sure I didn't get it wrong, and each result was within .05 of the pictured measurements.
