Has anyone replaced the front pipe on their exhaust? I have a 1994 Camry XLE V6, and I need to replace the flex pipe(the pipe going from the manifold to the ctalytic converter). I have seen it called a front and a flex pipe, depending on who I talked to. It looks like an easy job, just removing 4 bolts(with an air gun I assume), and replacing some gaskets. I just want to know if I am simplifying this job, or if this will be a nightmare for me to get the bolts off. If anyone has any stories to relate to me on their experience with this job, please let me know. Thanks. John
