The smell lasts for like 30 minutes of driving.
Did you do the install or did a shop? Do you have experience installing downpipes previously? Not questioning your ability, just trying to figure out whats going on.
My vrsf downpipes fit perfectly.
I think I'd recommend pulling both off rather than running one dp. Call tiago on Monday (or send him a pm on here over the weekend). He's a good guy and I'm sure he'll get it squared away for you
