Default 2014-2016 C7 Corvette Long Tube Header System w/ X pipe

Step up to full length headers and an "X" shaped mid-pipe without the hassles of cutting your old system off. Granatelli’s full length headers and mid-pipe are a direct replacement for the factory short style castings and intermediate mid pipe section, yielding a 26 hp & 21 ft/lbs. increase. Simply remove the stock units and bolt in your polished T-304 Granatelli headers. Best of all they include Granatelli's X shaped mid pipe and they are a direct match up to the factory rear system. No other parts are needed.
