Faction Fab has addressed the quiet stock exhaust on the 2019+ Subaru STI by developing a muffler delete. This system is a direct replacement for your factory mufflers, and can be installed in a matter of minutes with hand tools.
The construction of the axle back is made from 16 gauge 304 stainless steel, which is mandrel bent to ensure smooth flow. Attaching the muffler delete to the mid pipe is 3/8" laser cut flanges that will seal like factory with the supplied gaskets. The hangers are constructed from 1/2", and will slide right into the factory locations.To complete the axle back, you will have your choice of 3 tip finishes. These are slip fit, and allow you to fine tune the fitment.
NOTE: Polished tips are square (not side specific), burnt and black are staggered

Not loud disappointed
Just installed faction fab muffler delete twin wall on my sti yesterday but not happy with the sound...I will suggest to go with nameless muffler delete single wall tip much much better.
Install was quick and easy! Two bolts off for mufflers. Two bolts on for faction fab pipes nice and easy and they sounds great!
Deep, rich tone with good build quality and awesome tips.
I was hesitant to go with a muffler delete/axleback kit due to not wanting to be obnoxiously loud or having too high-pitched of a tone, but I wanted more volume and a deeper tone. After extensive research, I chose this system for its adjustable tips and hand TIG welds. The titanium burnt tips have a gold/blue burn to the double-walled inside that look amazing, the welds are clean, and the tack-welded placards are a nice touch. This system has a very deep, rich tone that is very noticeable but tasteful and not obnoxious and is without drone. I'm very happy with the quality and end result of this exhaust system.
I spent $1200 on a custom fabricated exhaust on a 2015 wrx which was totaled 😩 . After procuring a replacement 2020 wrx I wanted to try muffler deletes and I’m glad I did! These sounds 5 times louder then my expensive custom fabricated catback; also the tone and gurgle were aggressive and unique from everything else on the market for 1/4 of what I spent before. I had mine powder coated in flat black and they look amazing. Gurgles and pops for dayz. Also easy to install; I did not need to Jack my car. Highly recommend exhaust hanger pliers for this job 👍
