Any idea what brand j pipe this is?
Hello everyone. I am having a lot of CEL issues with my 2019 WRX. Thought it was an o2 sensor. Turns out it has what I think is an aftermarket J pipe. Any idea what brand this is and if it catted/catless? Have been running without a tune as dealer told me it was unmodified... Thanks!
