$250 for a hunk of rubber!?!

You can pick one up on Rockauto for $36 bucks. 2005 CHEVROLET AVEO 1.6L L4 Air Cleaner Intake Hose | RockAuto
Not sure what year is your car but you might want to check there. Dealer price is probably about $120.

I've already looked at Rock Auto, and the one they are selling is for the older E-TEC engine. If I were to try to use the older intake pipe, it wouldn't fit because the throttle body position was changed when they went to the Gen III engine. Instead of being up high and horizontal like on the old engine, they put the throttle body on the Gen III engine down low and vertical.

well, things have taken a turn for the worse; I got the dreaded P0420 code this afternoon. so my $250 problem just turned into a $2,116 problem.

damm, for those of us novice car mechanics what caused this P0420 code/what does it mean?

The P0420 DTC means that the catalytic converter is below a minimum efficiency level set by the PCM. To put it in simple terms, the stupid torn intake pipe just ruined my catalytic converter which in the 2009-2011 cars is $1800 from the dealer! (Because it's a Maniverter; the exhaust manifold and catalytic converter is one big unit)

Yikes I see what you mean. Can't believe it is that expensive to replace the catalytic converter. Will be dreading the day that happens with my 09 Aveo. It seems that like they set a trap with this car: An inexpensive car with very expensive parts to fix it!

It's unlikely that the broken intake hose caused your cat convertor to go bad. (I've had split intake hoses on most of the Asian cars I've owned and it never caused the cat to fail.) I recently changed the flex pipe on my '09. The cat converter is NOT in the manifold. It is in the first pipe that is farther back, rearward of the flex pipe. But beware - changing the flex pipe is a bitch of a job, because the flange connection of the two pipes becomes galvanized into one solid mass of rust. That means that if your cat is bad, you will need to replace the front flex pipe as well.

When this happens that the flange connection becomes completely rusted what is the best thing to do to be able to disconnect them? I ask this because I may need to change out the oil pan due to a possible leak in the gasket of the oil pan. I also have an 09 aveo and the flange connection that connects the oil pan to the catalytic converter is completely rusted over as well.

pretty much your best bet is to soak the fasteners in penetrating oil; if that fails, heat from an oxy acetylene torch is your best friend.

Your statement does not make sense to me. The oil pan is in no way connected to the catalytic converter or the exhaust pipes. You will need to use a hammer and chisel to separate the exhaust pipe flanges after you cut and drill the fastening bolts out of the flanges.
