I just bought the Fantom Racing pipe for my Rusty 2.5 and am having a problem with it. THe end of it were it goes into the rubber thing that holds it on is much smaller than the stock one. Why? I tried wrapping electrical tape around it but it still doesn't fit were well, and if I drive it will probably fall off. What is the problem?[sm=confused.gif][sm=drowning.gif]
