Stock Exhaust or Not?
So 3 days ago I traded in my beloved 335i m sport vert for a '13 xdrive 35i because as a newish mom, getting a car seat out of a two door vehicle sucked.
I did the trade at a dealership but after getting home and doing some digging, what was supposed to be my sporty mom grocery getter has a burger intake and a JB4 installed. Now I'm questioning the exhaust. I looked up info on down pipes and what the stock exhaust looks like and mine doesn't look stock to me but I need some more opinions.
Also, anything I should know about all of this? This is my first 4- door vehicle (I'm almost 36) but I've never tuned anything past a k&n intake on a Saab 9-3 vert a loooong time ago. My husband says to just not worry about it and drive but I'm curious.
