ok im having bit of a problem and cant seem to figure it out my car was running fine last week now it has no power can barely make it up hills and sounds like there is no exhaust coming out the back once so ever and the intake is very loud i am running the stock cat with srt4 duals can my cat be blocked cause me to lose power? i need my car for skool so if anyone can help me as soon as possible it would be a great help i replaced the map sensor and egr valve idk what it could be and i dont have money to get a new motor yet thanks to whoever helps me out

 

blocked cat... but sounds more like timing...

 

i didnt think of timing but its not idling differently or anything like that ill look into it and see thanks

 

Sounds like the cat to me. I blew one apart in an older Mopar of mine and it lost all power and made a loud hiss come out of the intake. And it didnt affect idle.
