What's That Smell?

[Hugh Jorgan]

I have a 2005 Dodge Magnum RT, 5.7L Hemi. When I get down on it, I get the faint stink of rotten eggs.
Is this normal, or do my Cat's need replacing?

I've noticed the same thing with my recently purchased '05 RT 5.7.
My thoughts: this is a result of the rear design of the car. The forward leaning back end of the Magnum pulls the air forward behind the car. You wouldn't notice it otherwise.

What gas do you burn? Regular is notorious for this.

I regularly use 89 octane with a 93 octane fill every 4-5 tanks.

It's just unleaded gas that causes this. What's unusual is the fact your smelling your own car, usually you smell the car ahead of you if they happen give it a lot of throttle. Not sure what's causing the exhaust smell to circulate & come back into the car.
