Question for all of you - I noticed something odd today. We went for a drive today and we returned i accidentally touched the left exhaust tip while unloading the trunk and it was hot. For some odd reason I decided to touch the right side and it was cold? Should the exhaust temps be exactly the same for both sides?

Is there a problem with my exhaust?

Thanks....

On T8 (and maybe T6 too), there is a valve on one side of exhaust pipe that only opens at higher RPM. So it could be cool if last few miles are just light driving.

You must've been a handful for your parents. :D

I went ahead and disconnected the plug to the right exhaust. So both exhausts work all the time. It might be a bit louder but that is ok. Any restriction in the exhaust will reduce power though it is probably not noticeable.

I see this as a regression. You're losing the ability to dynamically control exhaust noise for zero performance gain.

Luxury cars have this feature so you get to choose - quiet exhaust or sport exhaust. If anything, the exhaust could be a bit louder in POWER mode.

Yesterday I parked next to a BMX X5 or X3 (I don’t recall) but I did notice the left exhaust was black with carbon while the right side was shinny Chrome. So you are correct it looks like other manufacturers use the same technology.
