2017 For sale: Downpipe (Y-pipe) from a well-known American company ISR, almost new. I installed it for only one day because the headers and exhaust size did not match it. It was bought new for 1,173 SAR, not including shipping from America. Asking price is 1000 SAR or highest offer. The downpipe size is 2.75 inches and the outlet or collector is 3 inches.
