It depends on the match.... The new can may be a better match for back pressure, and if so it may create a better change in the usable power band. Lets hope so.

Wise move. Next get a misting bottle full of water and in low light, go mist the plug wires good.... Replace anything that arcs. This is to keep the new parts, mostly the cat in good shape.
Are the after market parts supposed to change the sound of the car?
Sounds sportier all of a sudden.
Considering you changed the cat, this would be expected. What happened was that the cat that was on the car collapsed and was restricting the exhaust flow. This didn't suddenly happen, it had been going on for sometime, it's just that it finally let go all together and plugged the exhaust. When you switched it out, you suddenly had a normally flowing exhaust again.
i took my car to the local oil changer for an oil change and also had them to change the spark plugs. Since then it sometimes
unexpected while driving will go into limp mode. went dealer and had fluid changed when not in limp mode drives like a new cars. if car sits limp mode goes away.. could a short or wrong spark plugs be the problem. 2007 jeep cherokke
I had a 2005 Ford Escape that went into the limp mode at 95K. Turns out the central computer (forget what Ford calls it) was bad plus new coils and plugs were needed. Ford wanted $2,500 with a new computer or $2,000 with a rebuilt computer. My local good guy mechanic did the job for $1,400 using a rebuilt computer.

I'm leaning toward a computer issue also.
A clogged cat should throw some CEL codes, as would coils.
There are ways you can reset the computer and see if Limp Mode goes away. I'd try that.
"Limp mode" is a term used to describe reduced power requested by the engine control computer, to prevent damage to a turbocharger from underboost or overboost. When this happens, cycling the ignition off and on typically resets the engine computer and normal power is restored -- until the next time a turbo boost issue is detected. It almost always involves the turbo control actuator or a faulty sensor, and not an actual problem WITH the turbo.
It is not a correct term to describe anything else, especially not reduced power in a normally-aspirated engine.
