It is said to quieten down fully uncatted BRZ exhaust systems.

Any experiences?

The Thermal people are quite straightforward about their product, which is intended for the elimination of droning, and told me not to expect any gains but also said that no losses have been measured. Honest statements.

In my case I'd be mating it to an Unequal Length cattless header.

Thank you.

Why wouldn't they just make the midpipe one piece, instead of using a cheap slip joint fitting? They used v-band on the rear section, why not v-band on the other one?

That alone would be enough to make me not consider this exhaust. Better options for the money.

It is the only one known to me that eliminates the droning. Good video at Goodwin Racing and those guys are known to be truthful.
