If you already purchased the STM Axle-Back Exhaust, you can purchase the rest of the cat-back system separately for a full upgrade! This *should* also be compatible with many other aftermarket axle-backs that have a 2.5" flange and bolts to the stock locations, but please confirm before purchase.

The STM Stainless Steel Cat-Back Dual Exit Exhaust for the 2015+ WRX and STi will bolt up to your stock or aftermarket downpipe and gives you everything you want out of a catback exhaust! Full stainless steel construction, gorgeous design and hand-fabricated in the USA. The STM Exhaust utilizes your existing exhaust hangers and includes all gaskets and hardware for a clean and easy installation.
