^^there actually is not much room to add another resonator. I tried, and I kept on bottoming out on it.
What on a GD do you think is the quietest? I have had 6 different ones, and by far the Apexi WS2 was my favorite. Maybe I should just buy the muffler and have a shop fab me a catback?
Seriously, the tone is freaking amazing, but so quiet at all the right frequencies when you were not on it.
I mean, come on, I know it is subjective, but I personally think this is perfect! Wish I could get this sound on my 15+

and on ELH, it's 10x better than any other setup I have heard. Especially at the low speeds-- it has this neat gargle/growl that almost sounds exotic.
