Not attacking you at all. I’m just trying to make sure people are informed correctly.
People could see your post and then immediately be turned off to trying their exhaust with the valve open, or be hesitant to buy an aftermarket exhaust.

Placebo effect. If it was a legit concern all aftermarket exhausts would keep the factory valve. We would also see people post dyno plots if there was a noticeable difference.
Im mainly going off of the unofficial comparison @savagegeese did. The lap times were very close and the ITS makes noticeably more power. With its extra compliance it hops curbs better too. Hopefully someone does a head to head comparison on a road course soon. Same tires is a must.
Smart that they don’t offer the Type S with Cup 2s. Otherwise I think there would be a very real possibility of the Type S being faster than the Type R at this track.
