I have Tahoe 2004 recently I have been smelling exhaust fumes inside the cabin, I took it for exhaust leakage and the mechanic said he could not find any leakage or damage to the entire exhaust system, so any help of why I still smell the fumes.
Are you sure they are coming from your rig? The fresh air intake is from the front cowl area so anything close by will get sucked in especially in colder temps as engines tend to run slightly richer for longer than warmer temps. Is the exhaust system stock? I have seen a few of these pop the welds on the muffler where the muffler shield is on top, you can't see it normally due to the shield, but during a cold morning outside you can see some exhaust escaping out from under the shielding during the initial start up, of course you have to be under the rig to see it and only on initial start. Good looking rig too.
