EM header extension pipes w/high flow cats

Our header extensions are designed to fit our EM long tube headers to the stock resonator on  LT1 cars or fit into the reasonator on an aftermarket exhaust system (Corsa, Borla, Magnaflow).  The extension pipes also work on L98 cars for those who want to add a crossover or upgrade to a true dual exhaust.  Our extensions come ceramic coated to match our headers.  The ceramic coating with protect the pipes from rust and keep the heat down under the floor boards.
