Motors are both 3.8 ltr but not sure if fitment. I would ask your shop. My gut says yes but can’t say for sure!

Apparently they will fit but may cause O2 sensor light.

From what year 991 Cup did these exhaust manifolds originate? And how were the cats removed? I like the outcome. Thanks in advance! Best Josh

They are from a '14 Cup and not sure how cats were removed but have an extra set on my Cup and they sound great. I believe they also fit a 997.2 Cup with the 3.8 motor.

Thanks! You read my mind. However I thought the cutoff for using these on a 997.2 is 2013. Can anyone here clear this up. When did the 991 Cups stop using the 997.2 Cup engine? Thanks again. Best Josh

All 991.1 Cup's have the 3.8l block and use the same 997 exhaust - 991.2 uses the 4.0l with the new exhaust that is not interchangeable between 991/997 generation cars.

It is not the year or body style that determines the fitment. Rather it is the motor size. These headers are from a 3.8 liter not the 4.0 liter on the newest gen of Cup Cars
