Rattling exhaust drives me nuts

[Niko97RS]

ok, me exhaust is pretty frankensteined

long story short when i start my car up i hear a rattle till its warm

and if i give is alot of gas and it shifts hard it kinda rattles

sounds like a heatpan but i dont think it is

a guy at an exhaust shop told me that its "doubling piping" on the downpipe of my drivers side header

what am i hearin!?

Re: Rattling exhaust drives me nuts

I have the same problem, took a quick look under the card and couldn't see anything obvious. I'd like to know this too......my cat makes noise too on takeoff byt this sounds more like a loose muffler clamp or heat shield rattle.

Re: Rattling exhaust drives me nuts

could be one of the heat sheilds, theres a few under there. pull the car up on ramps and shake the exhuast a little and see if it happens.

Re: Rattling exhaust drives me nuts

my car did the exact same thing and when i went to get my flowmaster put on the car he found that 1 of the welds under the car had open up towards the middle of the car so it was actually the pipes slpit open and rattling all over the place so after he welded it back it never made the niose agin and my car sounds great now :)

Re: Rattling exhaust drives me nuts

Mine rattled for a while, but I found out what it was. I put in the 3" flowmaster catback, and the bend where the piping went up over the rear axle, until it was warm (or when it rained) it would rattle against that axle, but now it bent itself in a little bit and doesnt do it anymore :P that might be what your problem is. If nothing else, check that little heat shield that connects to your tranny mount.

Could be one of those U-bolt clamps. If it's a little loose it might rattle until it warms up a little... idk could be lots of things

off topic, but i never downshift my a4 to second at anything over 40, and i rarely downshift it anyways unless i just wanna make my exhaust heard lol

Re: Rattling exhaust drives me nuts

Its probably rattling from that support under the drive shaft. Mine did the samething till i removed it. But they say I souldnt of removed it, oh well.
