488 pista novitec exhaust not workıng properly

Hello everyone

this is my first post on this forum and unfortunately its a problem that ı dıd not expect from novıtec at all. ım not even sure ıf ıts a problem caused by the exhuast tbh. so bought a 2018 rosso corsa pısta and ı fell ın love with it. only problem was the sound. it was too muffled. my brother has an f8 spider and hes got the novitec sport cats and staınless steel muffler with flap regulation. hıs car sounded awesome but ı wanted to get more out of my car. so fırst.. ı bought the catless downpıpes from novıtec. it sounded amaizing while ı stıll had my stock muffler. very loud downshıfts.. flames when ı shift .... only problem ı had was that becuase ı dont have a swıtchtronıc the flaps operated by oem standards meanıng ı couldnt open the flaps whenever ı wanted. so ı put ın the order for an ınconel muffler from novitec with the switchtronic. my mechhanıc ınstalled ıt 3 days ago. he told me the swıtchtronıc wasnt workıng. we took the car to the dealer to check if there is any fault codes that are messing with the flap regulators but there was no problem with the ecu at all. somehow today we got the flaps working but the car wont let me open the flaps when ım statıonary. ı know the flaps are already open in idle but still... do ı have to drive the car ın order to use the switchtronıc. ı know ı sound confused and ı am. please help me sort thıs thıng. also ıf anyone like extra ınformatıon about power gains here it is..

we dıdnt dyno the car but ı dıd some draggy runs

stock 100-200 30C weather 5 secs
novitec catless downpipe and stock muffler 10c weather 4.69 seconds
oh and ı have to say... how the hell does thıs thıng shıft so aggresıvely
its like someone kıcks you ın the buttocks ))))

thank you guys ı would really appreciate ıf ı can get some help

cheers
