I purchased a '26 that had this option. I believe it was a port installation. I didn't have a lot of choices on incoming LC's based on the color I wanted and no cool box option, so I decided to grab it. Have to say, it sounds like hot garbage. No comparison on fuel economy to stock exhaust, but this exhaust is not properly tuned for this vehicle. Heavy vibration sitting in idle, vibrates deep in the dash, moaning sounds in every gear before it changes gears. Terrible moaning at highway speeds. Brutal. I'm not opposed to nice sounding exhausts. My other car is a Porsche Macan GTS and it sounds beautiful, but this thing....
My question is to anyone that got a vehicle with this option, did you keep it, or install stock exhaust, or another aftermarket exhaust option? I'm definitely not keeping it.
