Hey guys I recently developed a ticking noise in the exhaust when I start the car theirs no noice once it's starts to warm up the ticking noice starts any one have experience this issue and feed back would be appreciated

 

Is it a metallic rattle, or a proper ticking sound?

A rattle could mean your flexpipe is failing, or one of the catalytic converter heat shields has broken loose.

A ticking sound may not be the exhaust at all, it could be valvetrain noise or another engine related sound.

Does the sound vary in intensity with the engine RPM?

 

I had my catalytic converter fall apart internally. It rattled at idle hot or cold, temp made no difference, at least in my case. New converter and flex pipe, all is well now.

 

No it's a constant tick and it sound like in the middle of the car as soon as the car starts getting warm the ticking sounds starts when turn off the car you still hear the ticking sound until it cools down

 

Our vehicles have stainless exhausts, & when I shut mine off the exhaust ticks as cooling...No problem there.

Same thing on a Bike I made stainless pipes for, tick, tick, tick..

 

You might try getting under the car, and bang on the converter and the muffler. It might help localize the problem. If its disassembling internally, banging on it should yield some rattling noise. Sleeper has a point, you may just be hearing the metal in the exhaust system heating and cooling. Do you hear it inside the car, or just outside? If only outside, I don't think I would worry much about it at this point.

 

A constant tick is just the metal expansion and contraction because of the heating up and down.
Now a rattling tickety, tick type sound. Probably something loose internally.

 

so i finally took the car to the local muffler shop and found out whats making the ticking noise is the resonator. any body had this problem before
