Yeah, I did that I actually removed the filters from the old head and from the replacement, cleaned and kept the best-looking ones. The solenoids are also super clean and the code I get is only for the exhaust one. And only on each start. It idles then I get brief surge or something, but it sounds more like a semi cut off, half a second and smooth as can be afterwards.
