This comes as a complete exhaust system from the turbo back. The pieces it includes are: race 02 housing/2.5" mid pipe/high flow secondary cat/2.5" catback exhaust with muffler. This is made for the RS hatchback model. This will fit the 2012-2017 Sonic RS 1.4L turbo. Reason for selling is I'm selling the car just wanted the factory exhaust back on. It is pretty loud but not overly loud, it sounds nice! You can hear the turbo more as well. I have all the clamps and everything needed to complete the install. I paid $1,200CAD in total to get it here, had it on the car for 2 months.
