Default Exhaust Issue, Not Passing 5k And Nasty Crackle

So recently I had an exhaust leak fixed on the crossover pipe, before it was fixed it didn't have much trouble reaching high rpms and I even had it at 150+ but now I can't even pass 5k rpms and it has a horrible crackling noise, i looked under and the o2 sensor plug that connects into the crossover pipe is melted to hell, ive also had someone tell me my cat may be plugged, I would just like some opinions/maybe a soulution please and Thank you.. My mechanical knowledge is limited I'm more of a body man. took the best pics I could get.

you need to fix that plug before you go messing with the cats,

that issue HAS to be fixed asap, your o2 sensor is not reading the right amount mixture and is throwing your car off and can lead to other issues if its not fix soon

once it's running normal again I'll try to get a video or a pic of the speedo for you guys, cause now I'm just as curious to why I can pull that much.

No sir, if you're doing 150 mph, I would not suggest taking your hands off the wheel for any reason.

Right bro, no need to prove it. The reason anyone would say anything is there is a speed limiter on the car at 145mph? The used to be a flash that would remove that limit so it could have been removed. I've seen an undercover tan/brownish Maxima in my neighbor looked stock until he lit it up and pulled someone over. Very sneaky.

I want to take a picture with that one, (side by side, not him behind me lol)

Good news on your car running right, you get that plug fixed then?

but I haven't got it yet I sent pics of it to a guy that makes them so I should hopefully have it next week sometime and I'll have it put on asap for sure just been driving in town only in it for work.
