The COBB Titanium Cat-Back Exhaust is un-matched in build quality, style, and performance. Utilizing Grade 4 titanium tubing, this cat-back offers high corrosion resistance and protection from impacts. Back purging ensures quality welds that will not fail due to contamination. The entire system uses slip-fit connections, allowing for a wide range of adjustment. Blued titanium tips add a distinct touch and offer adjustability. Best of all, this complete system weighs in at 24lbs assembled, nearly 50% lighter than it's stainless steel counterpart.


The COBB Titanium Cat-Back Exhaust for your 2011+ Subaru WRX or STI offers premium styling and quality. Other titanium cat-backs can produce a certain 'tinny' exhaust note, however, the build quality of this system provides a refined note more akin to traditional COBB Cat-Back Exhaust Systems.

Rated 5 out of 5 by from Titanium catback exhaust on 18' STI I just finished the install on my 18' STI and I can't say enough great things about this exhaust. This catback is absolute top notch, the build quality is incredible, it sounds phenomenal and it looks stunning! Is crazy how light this system is compared to other SS catbacks. Coming from a different catback brand, I can say the drone on this exhaust is much much less, almost stock like.

Rated 5 out of 5 by from Amazing Quality Installed this on my 2019 STI and could not be more pleased. The sound is PERFECT and is what an STI should sound like... perfect rumble without being annoying. Not only that, this exhaust looks incredible. The craftsmanship is top notch, which made install a breeze. Was able to install this solo in about an hour with no fitment issues. Could not be more pleased. Thank you Cobb for always delivering.

Rated 5 out of 5 by from The Best sounding exhaust by far I just got done with installing this exhaust onto my 19 STI and wow it sounds absolutely incredible. I'm running Nvidia catless downpipe and so with that combination it is very loud but certainly doesn't drone. Cruising you can hear the exhaust but it isn't too loud that you couldn't have a conversation with a passenger on the highway but open her up and wow people certainly know that you are coming! Love love love this exhaust!!!

Rated 5 out of 5 by from Highly recommend This Purchased for my 2019 STI series gray. This exhaust has exceeded my expectations. Great sound and light weight. Respectable noise level with anyone concerned about it being too loud. That was my biggest concern. It makes the driving experience much more enjoyable.
