Performance exhaust question
 

So here is my issue.
I recently just picked up a 2017 C300 that I love (Except for the lack of any exhaust note) the car has every upgrade imaginable (Night package,19" wheels,,sound system,pano roof,ect) Polar white with the cranberry leather interior. My issue is if I go with a performance exhaust how much will this hurt the resale value down the road as I would imagine the car could not be a "Certified Mercedes " with a aftermarket exhaust. It is currently a certified vehicle as I purchased it used.

Unfortunately I cannot keep the stock exhaust as I have no place to store it encase it needed to be switched out..... This is my dilemma as I usually trade my cars within 2-3 years....

Thoughts?

youll need to find the right person. most people buying a c300 will want it completely stock especially being newer. if it was an older car your audience would change and some mods could be acceptable to the right person. but the person who can afford a newer c class most likely will want it to be quiet and stock.

if you had a c400/43/63 that is a different audience.

i would say not stock exhaust will hurt resale value and or finding a buyer all together. mercedes would not take it in and if they did they would murder you with the offer because they would not put on thier lot and it would just go to auction.

I have the AWE touring. Its a subtle improvement. I don't keep cars long either. I kept my stock exhaust and will likely switch it back when I sell the car.
