exhaust pipe?

I have a 94' cav and recently took of my old exhaust pipes off.
I was able to put on the front pipe and a new catalytic
but i'm having problems putting on the new back pipe on
(the pipe after the cat). Can't seem to fit it in.
Anyone know what i could do?

if they are all stock pipes for that car then they will fit...make sure to get the car as far off the ground as possible to manuver the pipe over the axle and whammo you got it

thanks for the tip. I'll ask my buddy for his jacks.
