Exhaust Valve Mod

moff · 12-06-2019, 10:45 AM

I've tested the exhaust valve modification - currently using electrical tape. The results are good, it's far to quiet in Efficient so I am happy with the sound now.

I can't seem to find the link to the US product that I can buy to fit into the now empty connection points? It would be a better solution than tape!

Any link would be appreciated!

Also I've had the ASD switched off for over a week now and I actually think it sounds much better. Going to switch back on this weekend to compare.

Can I ask when you start your car is the exhaust button lit up? I ask as I noticed mine was last night I wondered if I'd pressed by mistake or whether it starts up in loud mode.

It’s always on. It doesn’t really work in Efficient, someone told me that it does ASD in Efficient.

In Sport and Sport+ it open and closes the valves.

But I’ve disabled the valves closing now so they stay open regardless. I’ve also got ASD coded out.

I just found these the other day. Plug blanks for the actuators.
