I've read that if you get rid of the resonator and the back box it gives it a tiny bit more noise if that's your jam, also helps with getting rid of restriction and the person who did it says it drives noticeably different, anything EA888 Gen 3B listed I think revo do a silicone intake hose and turbo inlet for them, there is the typical turbo muffler delete. I don't think any atmospheric dump valves will be available with it having a MAF sensor. I can't imagine there will be many difference between Gen 3 and Gen 3B (which you have) would be much different.
