muffler silencer question
 

Hey guys,

So, I just traded my GMPP Performance catback for an Ark N2 yesterday. I love the look and sound, but I was curious on if I could add a silencer to it for daily use sometimes to quiet it down a little.. I went online and found out that it was a 115mm tip, and I found a few 115mm silencers for sale on eBay.. Would this HKS one work? It looks like it simply bolts into the hole at the bottom of the tip.. True? If so, I don't see why it wouldn't work.. Any other suggestions? I see that one came with it factory, but I didn't get one with the catback.. suggestions?

Thanks!
