Just wondering if anyone is running that exact setup. I recently purchased both and the downpipe went on without a hitch. After that, I attempted to install the cat-back for three (yes 3) days to no avail. It just seems like something is off. When the front section is bolted to the downpipe, and the middle ('s') section is slipped on and put into the exhaust hanger, it makes contact with the heat shield above the rear axle. And there is no way what so ever that the tailpipe portion is going on. I've tried twisting it every which way to get them to align, but nothing. Right now I'm waiting to see what Magnaflow says, but in the mean time I wanted to check and see if anyone had these two paired together. I'm almost 100% sure nothing is wrong with the downpipe because the remnants of the stock exhaust bolt up and align just fine.
