Identifying which 4" single shot exhaust

[tta1401]

I'm trying to identify if I have the RJC or GN1 single shot. The muffler has no identifying marks on it. Any way of telling??

post some pics and I'll compare it to mine. I have an RJC system still in the box.

Here's a few pics. I thought the RJC came with a Borla muffler.

Awesome! That's what I ordered. Just making sure that's what I got. Looking at GN1 pics, I couldn't tell a difference. I heard it was an exact copy.
