DMH Cut Out for HHR SS
lady3 do you know where he is going to run the "open" pipe?
Just under the car, out the side, back,?
This is one way to keep the car sounding stock on the road and have almost no back pressure on the track (no compromise), sounds like a great mod!

The open part will face down towards the road, just straight under the vehicle. Really a great way to get more power by just a flip of a button. We did Lady3b's truck got 16 H/P more by opening it up on the Dyno stay tuned when I get back to the States around Thanksgiving I'll have it installed and re-dyno it...
