I’ve had a few different set ups. First was a flowmaster 4” merge into a corsa. Then a custom built y into a corsa. Then into a dual dual. Now American racing into a dual dual. It flows well, I only pick up 5rwhp with the cutout open, but the car rarely gets driven lately I don’t mind if it’s a bit more rowdy. And some of the packing in the muffler has found it’s way out of the muffler...

Full Force, Don't get too excited yet. You have to get a 3" to 3.5" adapter slightly enlarged on small side welded on your y-pipe. You also have to cut the 2.5" section of y-pipe off to lose the restriction. TSP will tell you it hooks right up, but it doesn't. If you have one already, good deal. If not, shoot me a note and I can tell you where to order one. In stainless, it wasn't easy to find.
