Yes I ordered the valve simulators and I also chose to keep my stock downpipes for now. I'll see how it sounds and I could always install downpipes another time. Do you like how it sounds with the non res downpipes better?

I lean towards the the non-res downpipes but the difference in the vids is so small I'd like to hear them in person. But that will probably never happen! haha.
