Hey folks. I just bought a 2016 TRD pro but did not get the upgraded exhaust on the platinum / 1794 version. What's the best after market cat-back exhaust to replicate the sound produced from the nicer models. I'd buy the same exhaust as what's on the Platnum if I knew excactly what to buy. Also, any concern that exhaust build for the 2015 won't fit the 2016 models? Thanks!
