has o/r x pipe and magnaflows. I dont think its leaking but i could be wrong. Since the car drives fine and nothing seems different other then the smell occasionally i can live with it unless it gets worse or start running bad.

 

^^^ With O/R's there's always going to be a smell of fuel...

 

Ive had the o/r for 9 months or so and just started smelling this smell. Had the oil changed and such early and had them look at everything and it all checked out so im not gonna worry about it.
