70 Dart exhaust tips
Let me make this clear -
I swear by Accurate Limited for exhaust systems that are well designed and executed. I have recommended them to many friends, but this one thing just drives me nuts.
First, these two pictures are of factory tips for a 1970 Dart 340
This is a picture of a correctly executed tip from the now defunct supplier - Stainless Steel Exhaust Tips of Florida
This is the tip that Accurate Ltd will sell you, which they say is actually a correct tip for a late 60s B'cuda
The box is too short on these and therefore the short box does not stick out far enough to avoid the majority of the exhaust stains that a correctly shaped tip would take care of. It never ooks right if the tip is so far out that more than the box is showing as the OP discovered.
