Even if it does smell like lilacs, the exhaust pipe is pointing out the rear and I won't be able to smell it while driving unless I pipe it into the cabin. So once again, what is the difference what it smells like? I'd rather be smelling gas exhaust than diesel if I had to choose but personally, I would rather not smell either. Until I hear people talk about it, I have never given a thought to what the exhaust smells like since I am not sniffing it for the most part.
