I know my Catalytic converter is going out because it smells like rotten eggs when i get on the pedal. How hard is it to do and How much would a shop charge?

Easy. And they wont charge anything. Because you're gonna cut it out and install one of ZZP's downstream O2 sensor simulators.
Or at least that's my suggestion.

What year? Because, anything '01+ you can't put an o2 simulator in there and not **** with the cat diagnostics in the PCM. You can get a universal high flow converter from Magnaflow off of EBay for like 50 bucks...and a shop would probably charge like 10-20 bucks to cut out the old one and weld in the new one.
Keep in mind, unless it is a factory unit, most of the time it'll still trip the SES light for a catalyst since it flows better than stock.

Will they cut the cat out or replace it? Its a 06 so i still have to pass emissions.

Just buy a 3" catted downpipe from ZZPerformance and have an exhaust shop bolt it in there for you if you don't have the means to install it yourself.
ZZPerformance - Go Fast... Not Broke | 3800 | Ecotec | Sonic/Cruze
Exhaust section...drop down for the cheapest, catted one.

ima check it out. im goin to the shop later to see what they say. i just dont wanna spend 300$ on a cat.
03-06-2012
Considering ZZP's catted 3" one not only gives you better performance and MPG's, but it's at least a hundred bucks less.
03-06-2012
I got a hookup at a shop so ima see which one will be cheaper getting a universal or doing the zzp method.
03-06-2012
Well, a universal welded into the stock DP would be cheaper, but it'd probably be cost effective down the road, especially with gas prices on the rise to help those MPG's out. I noticed a few more MPG's easily going from a totally stock exhaust to my 3" downpipe/3" catback setup.
03-06-2012
One more? on the zzp downpipe. should my exhaust size be 2.5" or 3. Its a 06 Grand Prix Base.
03-06-2012
2.5" or 3" will work, it's all bolt in.
03-06-2012
Is there a diffrence in performance out of the 2 sizes?
03-06-2012
Nothing that you wouldn't really be able to see unless you had the car strapped to a dyno in my opinion.
03-06-2012
Alright. Im gonna go with the zzp. Thank you so much for the help.
03-06-2012
No problem.
03-06-2012
Keep in mind..the ZZP pipe will likely set the engine codes as well.

I actually covered it LOLKeep in mind, unless it is a factory unit, most of the time it'll still trip the SES light for a catalyst since it flows better than stock.
