    "This was not for the average backyard mechanic. The removal of the the old system took around ten minutes. Installation of the new bolt in system three hours. The pipes leading to the exhaust manifolds were not bent properly nor did the flanges mate up. After some cutting, bending and welding the new system was finally installed." posted by: SP on May 2, 2011
