Made this out of an old mustang mid pipe. 2.5 inch stainless and the 3 inch pipe off the front of the stock muffler. Connected to a 6 inch round Magnaflow and to stock pipes. Worked out well I think. Mellowed out the bark of just the muffler but still super beefy without being obnoxious.
Ya that's the rear. To connect my little Magnoflow to the stock tailpipes. Gonna do the front next. Check out the pan hard bar in the lowering section I made also. Rear control arms and adjustable sway bar mounts are next.
