Hmf Titan exhaust question

Hey guys I know the ehs controller is the preferred fuel controller on here I have heard people say if you want any real gains get barkers and ehs controller. I have no interest in the barkers cause of the noise they make ( my state already is not very atv friendly riding areas are limited)so it looks like my only option is hmf for a exaust that isn’t crazy loud my question is if i order a Titan exhaust and order the hmf controller would there be a actually gain I can feel. I know it’s not the preferred set up but I don’t want the noise of barkers and I’m thinking of going with hmf for the tuner also just for ease of ordering a tuning. I am not expecting huge gains but hmf claims several horse power even if that’s exagerated I don’t see how it is not a noticeable gain.
