About this part
S-Type Cat-Back, fitment-checked
Covers both the Subaru WRX and the WRX STI across an identical 2015-2021 span, so the STI badge does not change the part number here.
The WRX and the more powerful STI are listed together on matching windows, 2015 to 2021 for each, which is not something to assume on a car where the two versions often diverge. Neither line carries a further qualifier. It is an S-Type cat-back, replacing the pipework behind the catalytic converter. An installation document is available to download, and it is the only Subaru in this group.
