Does Stage 1 Upgrade work on 2010 HHR SS?
I'm getting a new 2010 HHR SS, next month and I want to put the Stage 1 Upgrade on right away. I just want to make sure. I will also be putting the 3" Flow Master Cat Back on right before the Stage 1, does this make a diffence with the programming? Thanks for the help!!

I have no idea about the flow master though.

My SS started getting a bit louder at 10,000 miles with stock exhaust and IMHO is quite pleasing as is.

I put down about 30whp more with a stage kit and bolt ons then a guy with just the stage kit. THe downpipe will give you the most and the catback will open it up a little. Maybe like 5whp MAYBE
