Hello,

I wasn't sure if this is a stock 2015 Mustang GT exhaust or not the dealer isn't sure of what mods have been made. I am hoping a member can take a look and tell me if it looks like a modified exhaust.

Thanks

Chumley without more pics it's hard to tell, but I'm going to go out on a limb and say, Ford Performance by Borla axle back.

Would this void the warranty? How much horsepower would this add roughly?

AK_Kayaker

1. No

2. None

Ha ha ok so I guess it is just to make it sound better as long as it doesn't void warranty I am good with it. Love the 2015 Mustang GT and really love the car. The other change was that the previous owner got new tires and rims the tires are 275/40 ZR18 105W and the car handles fantastic.

Thanks the information I appreciate it.

Is the picture from towards the front, or the rear?
Meaning is that pipe clamp behind the rear tires, or up under the cabin behind the front tires?

It is from the rear behind the rear tires.

Warranty: depends on if the dealership is being jerks (they'd have to be able to blame the issue on the exhaust modification which would be pretty damn difficult ), but 99.9% "no, it would not".

Power: none, the S550 Mustangs have proper airflow at stock, so, unlike some previous models, neither CAI or exhausts really add power now, just changes the sound/aesthetics. If you want to add power/performance cheaply/easily, go with a tune - drops most people by around half of a second on their quarter times with the GT.
