Introducing the all new Ultrex Performance Ultimate Series Range of exhausts for the MY15-18 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 Cat Back Exhaust for the Subaru WRX & STI MY15 MY16 MY17 MY18 is a direct fit/ straight bolt on.

This precision made stainless cat back exhaust produces excellent power and a fantastic exhaust note. The system has been developed locally on our own MY15 STI for a perfect sounding and performing system. It features a big resonator built in to the mid pipe as well as 2 perfectly sized rear mufflers.

The rear 3.5 inch QUAD tips have rolled ends with either titanium look tips or chrome tips.

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.

We can also provide the matching WRX FA20 front pipe/J pipe OR STI Dump pipe for a full turbo back system and even more power.
