Catback Replacement ?

I just recieved my SW catback and have access to the autoshop on base. What is the easiest way to remove the old exhaust and what tools to use to cut it out. Thanks for any guidance mark

Shouldn't be any different than what I did with the exhaust on my Envoy. Grab a saws-all and make two cuts, one a few inches behind the muffler and another in front of the resonator. Remove the two cat-flange bolts and the three sections just come right off. (Spray a little WD-40 on the rubber mounts, if you have trouble pulling the barbs through the them).

When installing the new exhaust, use some WD-40 on the rubber/poly mounts before attempting to push the barbs in....makes life a whole lot easier and prevents damaging them.

tighten the clamps all the way after it is all installed and where it wants to be. the clamps i had some ??? on but figured it out. look at the stock hangers and they will look the same as the SW ones, might have to do some trial fits it would have been better if they had labled them where they go, it just slows the install down allitle
