I have deleted resonator. In terms of soft we have more stability and smother runs. In terms of sound U can hear spool and more drone (also decat armytrix). I had bms intake woith resonator delete and i had to remove it after 100kms. So much sucking noise even with soft aceleration arpund 2k rpms. It was so anoying. I strongly do not recomend if U dont want spund like subaru impreza on steroids
PS after removong resonator I had to remap my car as it lost 40hp from 440 to 404... now we have 444 but smoth and constant
