Sad video, at some point I unsubscribed to his channel but now seeing that he took the time and tried to clarify his dyno test I actually believe this guy is genuine and not a douchebag... probably he will regret of selling his GT4, but everybody make mistakes

I did that too. Which brand OPF delete did you install? Do you like it?

@Sausage416 With OPF delete and valves open and stock muffler, do you notice any unusual or annoying drone?

supersprint - opf delete is a must , on the North American cars the filter does nothing but add weight and restrict sound/airflow ,delete pipe is a must.

I really hope this is not the "drone zone" on this car because it sounds (no pun intended) that the unplugging of the vac hoses is a no-brainer given a OAP swap.
Each individual's tolerance to/definition of drone varies...to my ears, there is a low frequency resonance with valves open between 2250-3250 rpm that some would consider drone - easiest solution is to put in a valve controller unit like the one from Soul and have your cake and eat it too.

I don’t have a valve controller. I’m just on oem valve programming ,valves open around 4800 rpm in first and second ,no drones there.

I am not a fan of the sound on the new GT4. Was in a 2020 USA car yesterday, then jumped back into a stock 16 GT4. Hands down the 2016 sounds so much better.

Stock vs stock 981 sounds way better ,with a full exhaust 718 hands down sounds better ,more Motorsport.

Any reason why you picked Supersprint OPF delete?
Thanks

It was available immediately ,and the least expensive.
in theory all the ss delete pipe should all be the same.

Thanks. Cargraphic OPF delete looks like stock and comes with sensor connections and without filter. It’s only slightly more expensive than Supersprint. For Europe based owners it seems like a good option. Anyone has experience with these specific Cargraphic OPF deletes?
