Exhaust Pulse

Listening to the exhaust pulse when the car is cold sounds normal; a continual stream of exhaust gasses with a slight sound as it leaves the pipe, however after the car has reached operating temp and has been driven around for a while the exhaust pulse sounds spaced; ie: there is a few seconds gap between each audible pulse, although the gasses still seem to come out at a continual rate as when it is cold.

Hard to explain, ill try with a diagram.
_ is the exhaust pulse

* indicates no sound

When engine and exhaust are cold:

Audible exhaust sound
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
Actual exhaust gasses flow

When engine and exhaust are at operating temp:

Audible exhaust sound
_ ****_ _****_ _****_ _****_ _****_ _****_ _****_ _****_ _****_
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
Actual exhaust gasses flow

So what is causing this brake in the exhaust sound? And why is it only apparent when it’s at operating temp? It ends up sounding more like a dog panting then a car exhaust system. Is this normal for an EBII with the I6 engine and the standard exhaust setup?

Any info would be greatly appreciated,
Thanx in advance,
Defective User.

It would be mailnly due to the higher idle speed when the engine is cold. Once normal running temp is reached, the idle settles down to normal.

A few seconds is a long time between exhaust pulses! I must admit that I didn't think the I6 "pulsed" with the standard exhaust setup.
