Tell the world a little bit about your vehicle
Got this truck in February of 2013 with 82k, been great to me since day one. All I do Is regular maintenance and oil changes. I get compliments on the exhaust all the time, and it has nothing but the stock cat and custom piping with a dump. And she gets down too, will bury the speedo (120) no problem! I love this truck but if this cobalt ss doesn't prove reliable, ill be downsizing for gas mileage.

I bought a first generation motor from an RE HC 12", which many people have knock offs, there are only 250 first runs of this motor. I bought a 15" basket for it and plan on having PSI, which is local to me, rebuild the sub and redo the spider and all the soft parts. Ill have to build a new box to my guru's specs, and hopefully I should break 140db with my single 15 and still have room for a carseat. Read more »
