is it a bad idea?

[rppngears]

I bought a set of aftermarket powder coated tailpipes last friday and tried to put them on this weekend. Unfortunately, as usual this did not go very smoothly. They are not bent the same as the stock pipes and despite the reassurence from the shop I purchased them from that they will fit, I could not get them over the axle.

I am thinking about trying to remove a part in order to put them on, but I don't know if I should. I don't know what this part is called. I looked all through my Haynes manual, but didn't find anything about removing it and it only refers to them as arms.

They are the two arms in a v shape, which connect to the differential and to the frame of the car. I believe they support the axle. I figured if I support the axle on jack stands, then I should be able to remove these arms one at a time in order to put on the tailpipes. Will there be complications with this? Also when reinstalling them, how critical is the torque I put on the bolts? I don't have a torque wrench so can I just tighten them as tight as I can get them with a hand tool?

Thanks for your help,
