Last night i was driving around and then i just startted hearing a rattle come from the front of the car..it was pretty loud,
I got home got someone to rev it up and it sounded like it was coming from the back of the engine or where the x pipe connects to the manifold

Could the pipe just be loose?
Or is it a more serious problem?

I don't remember if there are heat plates (between the exhaust and the floor board) back there like there was on an old T-bird I had. Mine had come loose at one point. Jack the car up when it's cold and get under there and wiggle things. I wouldn't be too worried at this point.

If your car is lowered and have accidently taken a few speed bumps, it could possible be a portion of the catalytic conver has broken off in the cat assembly and is rattling. Try taking a rubber mallet and tap on the exhaust near the cats and note what you hear. My two cents. Good luck.

I have no cats,
But it only seems to happen when i reach a certain rpm like 2500-3000
Sounds like a bb in a can

there are heat shields on the cats. Mine rattled once upon a time. I spaced them back out by prying them with a screwdriver.

Click to expand...

Check for heat plates (shields) or maybe dust shields on your brakes.

Might even be bad timing (detonation).
