If anyone knows what could cause this please LMK

1) Odd rattling noise (sounds like a bolt is loose?)
2) Popping noise after 3K rpm. Sounds like fire is about to shoot out of my exhaust. Does that mean im running rich? or is it normal?


Thats about it really. If anyone knows anything about these just let me know so i can take it back to the shop and tell them to fix it.

 

Loose bolts? Pipe is hitting the heat shied? The only way to troubleshoot is put the car no a lift with the motor running.

 

i think that's not to out of the ordinary with test pipes. the sound quality of your car goes down with them.

 

The popping noise is normal and some, including myself, find it a positive
