I am in the process of installing 4-5" exhaust. I have the first piece in and am trying to install the crossmember pipe. The flared end of the crossmember pipe is just slightly larger than the end of the other piece and will not slide over. It looks as though to make the crossmember piece clear the crossmember it has to go over the first piece instead of just butting up to it and using 4" clamp to hold in place. Am I right or just seeing things screwy? If it has to slide over then I may have to find a shop that can spread it so it will fit. Any help is appreciated! I tried calling John but he is not in at the moment. Thanks David
