I have a 2017 Ram R/T with 64K miles. Whenever I start up my ram when it’s cold it starts up normal. But after about 20 seconds it starts making a weird sound. The sound goes on for about 2-3 minutes and then goes away. Noise only comes on cold start. I replaced the exhaust manifolds last year. Both sides. Noise comes from under the engine. You can hear more on the left side of the engine.
