Eric Lange

Perfect fit, arrived very fast

Simple and easy to install

Used this adapter when installing my ETS catback on my 2022 WRX. Should hold up just fine until the time comes to upgrade the J-pipe later.

Daniel Franklin
Worked great

Used this to mate a Cobb Gesi downpipe to an Invidia exhaust. Worked perfectly, no leaks at all

Michael Lee
Simple and fast

Bought this adapter due to my exhaust leak. It’s a well made product that fit perfectly and sealed up my exhaust.

Keep it simple stupid

Piece fit perfect. Figment issues never crossed my mind. Came with all the hardware and gaskets you could need. I didn’t even use the gaskets from the catback kit I got because I believe the gaskets provided with the adapter are slightly better
