It is as good as described. ( you got yours for $4 less than I offered )
One thing I didn't do, and still may do : The OEM has a rubber bumper in the center that is intended to prevent the muffler from flying up and hitting the bumper cover when on really rough roads. The OBX has an area for this, but no hole to mount the rubber bumper.
I may drop mine and drill a hole and mount the rubber bumper.
Not looking forward to it.
The entire swap process took me 2 hours : 1 hour and 50 minutes of that was getting the 2 muffler hangers loose to remove the OEM muffler.

HINT :
1. Jack up the rear and place on 2 jack stands.
2. Remove both rear plastic diffuser pieces.
3. Use the jack to now raise the muffler as high as it will go to remove as much tension on the muffler hangers as you can
4. You can now go into each side in the diffuser area and get the hanger donuts off.
( Don't try to get the top part ( on the body ) loose, get the part on the muffler off.

When you install the new OBX, go ahead and tighten up the clamp, but leave the 3 bolt collar ring loose. Have someone do an alignment to get the 2 oval tips even, then while they hold it in place, tighten up the 3 bolts.
