SS Replacement Outlet Exhaust Downpipe for Chevy 05-10 Cobalt SS HHR Non-Turbo

The most restrictive part of any exhaust system is the catalytic converter. The stock catalytic converter is meant to filter the flow of exhaust gases to reduce the amount of harmful gases into the atmosphere. Because of this, lots of potential performance is restrained. Down Pipes eliminate the stock catalytic converter and reduce exhaust backpressure. By maximizing exhaust flow, this downpipe allows the turbo to spool up and build boost quicker. The result brings out the vehicles performance potential by giving it a free high flowing exhaust system.
