Hey everyone! So, I have a skunk2 system on my 13' Si coupe. Pretty much need a recommendation on what I can do to reduce the sound as the silencer sounds aweful. I purchased the system for $100, so I'm willing to fab something up if I can. I've heard people saying putting another res on...but could I cut the muffle, replacing with a magnaflow or flowmaster? Anyone done this?

You shouldn't have to cut it.

...didn't it come in three pieces?

Just remove the muffler portion and add a megnaflow muffler.
