Uber noob question. Im going with the speed daddys. Where exactly does the header stop? People say it replaces your cat so youll need to weld a new cat. Thing is my currdent cat is fairly new can I just re use it? Or does the header stop before the dp? If so ill just pick up a new dp. Also whats the best method of installing the rear header? Through the bottom, hoisting the engine up, or through the top? One last thing do the header pieces get welded onto eachother because it doesnt look like they get tightened with bolts? Thanks guy would really appreciate your responses. Its a 97 grand prix gtp by the way.
