From what I read when I was researching for my exhaust was that almost every C-HR exhaust works on a Corolla, but not every Corolla exhaust works on a C-HR. Some require slight modification such as a small bend or an exhaust hanger modded. I went with the Remark dual exhaust. Was wanting the quad tip they offer for the Corolla, but they wouldn't tell me exactly what needed to be done for it to fit the C-HR. Hope this helps some.
