bro, the salafis are the staunchest in adherence to the sunnah and if you dont see that then you have not sat with them in their gatherings. If I go to a sufi mosque and mention a sunnah that isnt practiced "back home" they will outright reject it, if I bring any sunnah to a salafi masjid they will all race to practice it. That is somethign im 100% certain about. What you have said is teh opposite of reality. Sufis like to busy themselves wit things that simply arent the sunnah
