I have the Msport rear bumper on my car. I didn't know you could just swap out the diffuser part, though. Learned something new today. lol The ones pictured are a little too garish for my liking. I'll have to find something that looks like the stock one with the opening for quads. I'm pretty much sold on the Remus after watching marcus321 vid. Sounds deep and throaty. Deepthroaty.
Now to start checking between the couch cushions for spare change!
