My Car Has A Rattle Under The Car I Think It's Prolly The Exaust Anyone Else Ever Have This? Is The Exaust Piupe Supposed To Touch The Thig In The Middle Of The Exaust Pipe By The Cat Cuz I Looks Like It's Not?

 

It could be the exhaust if it isn't welded. My '02 Z28 has corsa exhaust on it and for awhile it was welded...used to rattle like no other against the driveshaft, especially with a rough idle. It could also be clutch chatter if you have an M6...try sticking in the clutch and see if it goes away. Those are the only two things I can think of at the moment. Good luck.

mine rattled against the pointless brace up by the tranny, and where it turns up by the axle in the back, my g/f's rattled where it turns down once it has passed over the axle, so maybe check all of those points

 

yea its like by the tranny i would say it's kinda loud and im really getting upset with this car. i bought it on ebay with 58000 miles on it and within 2000 miles i have had 2 replace the radiator, battery and the alternator 4 times it keeps dying so i keep having to change that 2..... uhhhhhhhhhhhhhh

 

I have a rattle. Though it was the exhuast mount. tightened it.... wasnt. removed the entire exhaust.. YES it worked.... no wait it's just too damn loud to hear... yup it's still there. Passenger rear wheel well. I dont know what it is. It's driving me insane.

 

While the car is cold, get under and tap somethings with a plastic hammer. Make sure you tap the cat well too, the internals are prone to cracking and rattling inside.

Did you read my reply to your last post about the alternator?

 

You need to get under the car and have a look. Run your hands along and around your entire exhaust (when cold of course). Any place in your exhaust that is touching something else might be it.

Like me however, if nothing is touching. Bang your cats with a rubber hammer or the palm of your hand. The internals of a cat can break apart and rattle. And I mean rattle. Mine did this and I must say it was the most annoying sound I have ever heard from my car. It sounded like a rock in my exhaust.

If you narrowed it down to your cat.. replace it. Mine finaly gave way and clogged completely.

Ef'n exhaust shop that welded my cat on used so much slag that it probably over heated the cat and it cracked

 

YEA I'LL TRY THAT. I think im just gunna go without the cat anyway when i get my exayst done. I also can say that the sound is so annoying that i haven't drivin my can because of it! IT SUcKS!
