Since ive bought my car about 3 months ago, ive noticed this smell when i get out of it, Its gonna be kind of hard for me to describe. But its just a really rich smell, not like coolant though. i was wondering if its because my car doesnt have a cat on it... The guy i got it from just like put straight flowmaster pipes on it with no cat. Would that be making a nasty smell? Alright thanks...
