Introducing the all new Ultrex Performance Ultimate Series Range of WRX & STI exhausts for the sedan MY11-14 Subaru WRX and STI. This all new range of exhaust systems offer unparalleled quality and performance, whilst undercutting competitors systems by hundreds of dollars.
The Ultrex Performance Ultimate Series WRX & STI cat back exhaust for the Subaru WRX & STI MY11-14 sedan is a straight bolt on.
This precision made stainless steel turbo back exhaust produces excellent power and a fantastic exhaust note. It features a big resonator built into the mid pipe as well as 2 perfectly sized rear mufflers. This system sounds awesome and makes bulk power.
Ultimate Series WRX exhausts are crafted from 1.5mm thick stainless steel which is up to 25% thicker than some competitors inferior exhausts. This thicker stainless steel produces a deeper meaner exhaust note.
The rear 3.5 inch QUAD tips have either black chrome, titanium or chrome tips with rolled ends.
This is a 3 inch system that splits to 2.5 inch from the y pipe to the mufflers.
Quality gaskets and bolts are included.
This is an absolutely precision made stainless steel exhaust system with quality tig welds throughout.

Awesome exhaust!By: Sam on 26 April 2021Quick delivery considering it came all the way from Perth for starters. This exhaust is amazing, its not too loud and it definitely isnt obnoxious. Just a classic boxer rumble with respectable grunt! As it's a catback, it was easy to install. It took me and 3 mates around 2.5 hours to install, but we're hardly knowledgable and we were able to figure it out with ease. Someone knowledgeable would have it done twice as quick for sure. Great product!
Installed on my 2012, with Titanium tips.By: Daniel on 28 July 2020Just received this today and installed within an hour of the package being dropped off. First off shipping was extremely quick, ordered on Wednesday night and was received by Tuesday the next week. The packaging was also good quality to protect the exhaust, a small part of the box had torn with a small bit of flange sticking through- but it was wrapped well enough inside the box the have no actual effect anyway. The quality of the exhaust is excellent, as is the included hardware for mounting. Was really happy with the design and fitment of everything. Install process was very easy with everything supplied and fits perfectly to the car. I bought this exhaust after speaking to someone from Ultrex on Facebook (very communicative and helpful, even though it was well after normal business hours) and describing what I was looking for. Basically I wanted to bring out the exhaust note of the car, but not to be excessively loud and still a comfortable cruiser. I daily the car and work at odd times, so I didn't want an exhaust that was going to give me a headache at 3am or wake the house up. This exhaust is perfect, it has a nice little rumble on idle but not overly noisy compared to stock. Just accentuates the deep note. When cruising, it is nice and quiet- zero drone. Under acceleration, it has a really nice note without being too loud. Really just adds the exhaust note that was missing from stock. I may consider changing up to the TBE at some point if I want more sound, but right now for a daily car. This is perfect without being too much. Highly recommend it.
