How do I replace muffler in 2002 grand prix se?

if the exhaust is all one piece meaning no joints/connections then cut the old muffler out by cutting the pipe in front and behind the muffler leaving enough pipe for the new muffler to slide around the exhaust pipe and then using muffler clamps clamp the pipes in place on the muffler until its tight.

Convert dual exhaust on 99 sunfire gt to single?

You can cut out the Y pipe and replace it with a flex pipe from parts store, then clamp each end of the flex pipe, the pipe diameter will be 1-7/8 or 2 inch, also for the pipe replacement piece would work from a sunfire or cavalier from 1995 and up, might need to replace the muffler strap too. as it can break from rusting, if not already rusted and broken.

I have an 03 grand am GT that I bought 3 months ago, its been a great car up until a few weeks ago, it starts and runs fine but when I hard accelerate it bogs down, I cant make highway speed 110 kmh, when...

The screaming and high RPM means the transmission is downshifting as it should be.
The code 420 is for catalytic converter low efficiency bank one, which could be an exhaust restriction or a fuel problem.
The easiest way to find out if it is a restricted exhaust is to remove the exhaust system where the cat connects to the pipe from the motor and test drive it a short distance. The restriction could be in the connector pipe between the cat and the muffler, or inside the muffler. A mechanic could also use an inferred heat thermometer to check the pipe temp from the engine back to the muffler while the engine is running.

I need to know where you would locate a o2 censor and 2 map censors for a 2000 Pontiac Grand Am..V-6? I have no idea where to even begin looking on the car.

The O2 sensors are found on the exhaust pipe. They screw into the pipe and has wires coming off of them. The MAP sensor has a 3 or 4 wire plug with a vacuum hose connected to it commonly found on the intake or firewall.
