So i decided to throw on my set of xs power catless downpipes. Review of those is coming but i figured id give a quick opinion about them through the FI Exhaust and link a few yourube sound clips.
Cold start with valves open
Valves open revving
Valves closed revving
This thing is incredibly loud with no cats at cold start. Very aggressive. With valves closed it does go into sounding like a prius either it gets really nice and deep sounding. I will still try to get fly bys when i can. With the top up and down.
