If you want to put these on an Interstate. Here's my method...
These are the same billet stacks that I cut a "V" opening to accommodate the I/S pods. I did not want to start bending pod engine guard mount tabs to reposition the pod to fit with stack installed. It's a clean and virtually invisable modification method and does not create a tweaked pod position.
Aeromach' stacks are CNC machined from a solid block of billet aluminum, not cast aluminum like the other guys.
I used a Dremel cut-off wheel, fine filed the cut & polished the cut on a polishing wheel. You'd be hard pressed to see where the chrome ends, especially if I had filed the cut and sanded a little better. The chrome has not chipped or peeled at the cut edge. I don't know for sure, but I doubt I would have had the same results with the other's cast units. The cast units, I imagine, would be more brittle and possibly prone to fracturing and/or breaking.
