Smile Wedge Tuning Cold Start Noise Reduction Review with video

Some of you have seen this option on MHD and may have wondered if it's worth the try. Believe me it's worth it if you have aftermarket exhaust with downpipes. I had to give it a try after going catless with PE modded mufflers. I was hesitant at first because wasn't sure if it would do the trick but after trying it I won't go back.
Not only is it great on cold starts but it also suppresses the sound on all warm starts as well. Nice feature if you have pissed neighbors from your exhaust terrorism or girlfriend who thinks your exhaust is ricer. Either way can't go wrong and here's a video:

It has nothing to do with that because my car has had rough cold starts for a while now after being pushed hard the previous night.
But, I wonder how it does effect the cold start warm up. Will it take longer to warm up with this option engaged? Maybe someone can chime in?

Love the feature that MHD offers never unchecking cold start!
