Clicking sound from exhaust when car is warm and when car shuts off

[aznfab213]

I have intake, dc sport 1 piece 4-2-1 header connected to 2.25 exhaust piping leading to a muffler.

When I am driving, I keep hearing this clicking sound from the exhaust area. It sounds like something is expanding or contracting. When I come to a stop and shut off the car, the sound continues for a while then just stops. Is there a fix to this contracting and expanding sound? I am getting sick and tired of hearing it.

it is normal.

All cars do it.

Its the exhaust shirking back down to normal as it cools.


Yes you can stop it.
1.Have no exhaust/headers/anything..
or
2.make your exhaust out of non-metal parts.

try taking the heat sheild shit off if it still has it on the exhaust system, just need a 10mm ratchet and rip them all off. they can sometimes cause annoying noises and rattles etc. i did this and my exhaust doesnt have any odd noises now and it had heaps before haha

In my particular case, I hear the clicking while driving also. This is a custom 2.25 pipe that was made. There are no heat shields on there.

check if something is rubbing metal on metal?

Could be something loose on the exhaust.. I would try checking the simple thing first..
