My GMMG bolted right up to my 3" ypipe with no problems at all. But I have to warn you it will rasp around 2200-2700 rpms with an ORY.

I'm sure there was other mods to the car. There's no way he'd gain 15hp by installing magnaflow over gmmg.
My magnaflow muffler doesn't look like the one pictured but I did go from a 13.8 at 99.8 MPH to 13.20 at 105 MPH after replacing the stock muffler with it .
