Any suggestions? preferably systems that work with the stock valve control system. I will be using the stock downpipe and keeping the catalytic converter since I'm in California. Any suggestions would be appreciated. Thanks

I was checking that one out earlier, but wasn't sure if I needed to use a custom valve controller/piggy back.

I want the exhaust valves to behave as factory, so the exhaust valves change between drive modes instead of a valve controller remote.

you can re-use the stock valves. i also recommend checking with them directly

How?

First off the Valvetronic has two valves when the m240 stock exhaust only has one.

Second the valves are completely different and are pneumatic valves.

Third the valvetronic ones are welded in. It’s not like you can swap them.

Fourth, not certain about this but valvetronic valves are most likely larger in diameter since the piping is larger than stock.

What I meant is that if you dont use their controller, the valves should work like OEM but as I mentioned, it's best to confirm with them directly.

The photos I’ve seen of their valves it looks like they use completely different connectors compared to stock.
