I took off that crappy pipe today, went to home depot and bought a rubber 3 inch pipe coupler and put it on it to extend it more towards the front of the car. I can tell already a pretty good power increase since I have done this. She is alot more peppy than usual. I held the old pipe up to the new coupler and theres a little over an inch difference ( compared to the narrow end of the stock pipe, which I think abouts to alot more flow. You can also hear it sucking in air from out side the car with my fans running. It worked out very well. As for gutting it my 94 box has nothing in it so gut.
