This exhaust only fits the "SS" rear bumper cover.
We recommend no resonator for turbo applications.
United States United StatesThis exhaust w/o resonator is perfect for the turbo SS model. It isn’t obnoxiously loud but is definitely audible when you want to hear it. Nice deep rumble at idle and low rpm, doesn’t sound raspy on the top end and quiets down nicely on the interstate with virtually no droning. Fit was great install took less than an hour.
United Statesan easy install overall spent most of the time removing the old exhaust with a Sawzall :) the piece that goes into the muffler section was a little tedious and didn't go in easy as the rest of the pieces, other than that a nice piece of work!
New to the ecotec world I accidentally ordered a cobalt ss exhaust for my hhr ss and then a couple hours later came across the hhr ss exhaust. Thinkin to myself I was *******, I called ZZPerformance customer service department and Ashley had the issue handled for me in 4 minutes. Thank you so much I definitely will be a repeat customer just based on how pleasant my experience has been. Thank you again.
United StatesFantastic sounding exhaust system. I am lucky enough to not need a muffler for a state inspection so I got the muffler delete
