69 AMX

Looks like the Sidewinder and the Trendsetter are a little different. Sidewinder appears to cut in though the dogleg of the fender down in the rocker area. It’s been my experience that sidepipes are generally loud.
Exhaust goes completely under car, the area you see is a cover that attaches to the lower fender as the bend of the exhaust pipe travels to the side pipe muffler. The exhaust travels along the pinch welds rocker underside, the exhaust shield on side pipes attach from original rocker moulding screws. Completing the look. The sound is amazing. In my opinion.
