Recently my car started sounding like a subaru out of nowhere and i found out that my headers were cracked. ( at least thats what i thought) so i was getting no back pressure so i finally just bought new headers and put them in and i turned on the car and it sounded like a helicopter....just didnt sound good at all. i dont know what it could be. anything would help thanks.

heres a video. i dont know if you can see it though but you can still hear.

exhaust leak and cylinder misfire, do a power balance test.
