hello! i'm looking into upgrading the exhaust system on my 1996 xj! But my xj has a 1994 4.0 engine in it, will there be a problem in fitting an exhaust system? furthermore i would like you to tell me what is the best exhaust system out there quality-wise and performance-wise! i'm looking to change it completely because my manifold has cracked! flamemad: ) thanks..nick
