Did you order an exhaust system made for headers? the original exhaust manifold ends half way down the engine block, The hedman headers collectors end under the footwell. Probably around a foot or more difference in length between systems.
Its the first piece that is made different in both systems.
You should be able to exchange the first pipe, ( from factory minifold to header collector).make sure you tell ecklers whose headers your using along with part number , collector size, probably bolt pattern size on collector. manual or auto trans.
Someone posted that "allens stainless exhaust" makes the systems (I dont know).
So dont go cutting any pipes until you get the right one (first/front pipe )
P.S. you should have posted in the exhaust topics instead of heating/cooling section, (more answers)
P.P.S. allens should be able to fix you up if ecklers wont
