Be careful of what you wish for. I had the Cobra Six-2-Six and the Two Bros Racing Comp S. Both proved annoying after awhile. It is a constant hum from the flat six and by no means a rumble like my previous Harleys. Kind of like the Asian cars with the aftermarket exhausts on them. If you listen to tunes, you will regret it. I sold my Cobra for the TBR and still wasn’t satisfied. Sold the TBR and went back to OEM. Radio volume went down from 24 to 15 and much happier when cruising with the silent exhaust. Plus fit and finish are superior on the OEM. T304 stainless steel canisters with chrome shields and heavy duty clamps. Everything fits like a glove. Aftermarket proved heavier with okay fit.
