Milltek exhausts for the Subaru BRZ 2.0 and 2.4
The first-generation BRZ 2.0 has two catalysts, and Milltek offers a cat-back from each. The secondary cat-back starts behind the second catalyst, so both stay in place. The primary cat-back starts behind the first and replaces the secondary cat section, making it the louder, motorsport-oriented choice. A separate over-pipe completes the 2.0 range.
For the BRZ 2.4 built from 2022, the secondary cat-back is the one system listed, so both catalysts stay in place.
Subaru Impreza WRX and STI cat-backs
Each Impreza system is matched to one era. The 2001-2005 cat-back fits the 2.0 Turbo, WRX and STI of that period, the 2014-2021 system is for the WRX STI saloon, and the WRX VB 2.4T boxer cat-back is listed for US-market cars from 2022, so check the spec of an imported car before ordering. All three start behind the catalyst.
Resonated or non-resonated, and tips for your Subaru
Where a Subaru system is offered both ways, the resonated version is quieter with less drone on the motorway, and the non-resonated version is louder and sharper. BRZ systems use GT-115 tips and Impreza systems GT-100 tips, in finishes such as polished, titanium, brushed titanium and Cerakote black, with burnt titanium on some GT-100s. Compare them on our tip styles page.
