Any better recommendations Than The Renntech EVM?
I am considering ordering one of the Renntech EVM's below. Just wanted to check with you guys if there is a better/different option out there for being able to fix the exhaust valves open on demand (for cold starts for example).

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

Yes, check out automotive passion they sell the same module for a lot less. I get the feeling they might make it for Renntech. The remotes are the same and they both install the same way under the passenger foot well.

"If your car is equipped with factory exhaust flaps, with or without a center console button to open or close them, factory settings do NOT allow the flaps to fully open unless certain speed and/or RPM have been reached. For example, while cruising the exhaust flaps will never fully open!"
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.

Base GT's did not get this option I don't believe, only S and above. I think you would need to add the valve system to your exhaust all together in order to get this feature.

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

Yeah, I was doing the same, but in a lot of instances it would start up far too quiet for my taste, and sometimes embarrassingly so when at car shows with a lot of cameras on you. Cold start is often glorious, and then after sitting at a meet/show for an hour or two, it always starts up super quiet. Going to go the EVM route as well to bypass this.

I am going to order this one and see how it goes. Will report back.

I don't, but the first one I linked plugs in, and is controlled through the stock exhaust button. From what I can tell, when you have the button turned on, it opens the valves fully, and when you turn the button off, or go into comfort mode, it closes them. A little less customizable than the other two options, but no external remote needed.

Hey guys, I have the ASR module ordered from the Automotive Passion website.
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
