What are you guys think about the catless Valvetronic design system?

Curious to hear your guys take on the system


Current setup: Test pipes and Oem Mod

I am enjoying the Valvetronic Designs catless central x-pipe with valved rear section so far. Super loud with open valves and it sounds just like stock with valves closed. Going to add another pair of resonators to tone down the sound a bit more. Overall I like it a lot better than my previous setup (OEM mod and test pipes).

Thank you I appreciate it

I added the extra set of resonators for a quad resonated x pipe with no cats. Sounds much better with no rasp:

IMO any of the valvetronic style exhaust need vibrant resonators or else it's just a bad sound. I have 4 on my armytrix and it's way cleaner
