Any better recommendations Than The Renntech EVM?

As gimmicky as it is, the "emotion" start on the facelift cars is pretty cool TBH.

Had no idea. I've been turning the accessories/power on, hitting the exhaust button to open valves, and then starting the car.

I think what their statement implies is that when the car is cold/warming up the valves stay closed until the car is ready. Their EVM gives you the ability to bypass that process. Who knows though they are the experts after all.

Also seen this option, that doesn't require an external remote.

I have a base GT roadster but with the performance exhaust and button.




It is the exact same thing as the Renntech module. Renntech is merely just the US distributor for ASR, except they slap on their logo and double the price. ASR used to sell directly to the US but they don't do it anymore.
The remotes give you the option to 1) keep valves 100% open, 2) return to normal function (PE exhaust button works), 3) keep valves 100% closed (which shouldn't ever be used as this is bad under heavy load)
It is over 2x the volume increase at idle and around town. The is also a significant increase in deep bassy rumble. There is however obviously no difference at over 4K as the PE valves fully open under stock operation.
Overall I am pretty pleased with it and this is how the cars should have sounded from the factory. Nothing beats it for the price. Only regret is not doing it sooner. First time I installed it I had people with cameras/mics coming up to the exhaust to film at C&C which usually doesn't happen for my sedan which is lower key. Good stuff!

Did you install yours yourself or have a shop do it?

Narrower tires (back rims might be smaller as well, not sure on this)
no painted calipers (unless ceramic)
No dynamic plus package
no crested armrest
i believe the rear differentials are different (electronic vs mechanical)
manual adaptive suspension vs interactive
