Its also meant to seal during engine torque movement.
I have this same exhaust also, I thought it was discontinued.

How do you like it? I originally wanted the full race, but I'm deciding to get the thermal when I can afford it. Open to other options though.

Sounds pretty good. low rumble when started, a lot lower sounding than stock. WOT is pretty loud but I am running the Buddy Club header, along with the Buddy Club test pipe modified with Random technology HFC installed. Originally I was using CT-E header, Random Technology down pipe and HKS. Big difference in sound

I will also add - i think this is the best looking exhaust available for the USDM chassis. None of the others did it for me.
