2006 Cat-back cautions

[RichLockyer]

Just got out from under my new '06 Duramax and the pipe connection behind the cat is no longer a 4-bolt flange. It is now a sleeve type coupling. I don't know if there is an off-the-shelf cat-back that'll work or not.

i wish my truck had a flange setup.

\all my pieces are sleeved together and then clamped. :cussing: I tried to pull the cat last weekend to gut it but coudln't get the pieces apar in one are so had to give up and now have an exhaust leak from not putting the clamp back on right, or something :cussing:
