Sound is awesome; my camera mic did no justice. The sound is very similar to your stock Exhaust, but it is much louder,deeper, and lets the engine roar. Sounds much like the Subaru WRX STI. "NEVER sounds like Weed-Eater Exhaust."

Auto HHR SS Turbocharged Launch
Both launches were on wet roads so the launch control didnt work well just causing me to light up the tires. I will do another video when the roads are dry. And Yes the first launch was a little shaky cause I had to go around a turn (and I dont have my headrest camera mount setup for the HHR cause its in storage).
