They are right in the middle of the exhaust trying to make a 90 degree bend. Of course you will have to figure out some ... Webabstract = "With the new pollution control rules and surging requirements for the increase in efficiency of the internal combustion engines, designing the exhaust manifold has become a growing area of interest.
