Which aftermarket exhaust is the quietest? In what order would you rate them from quietest to loudest? I'm considering Injen, TRD, Borla and Magnaflow.

Now in order to reply I'm hoping you have heard them in person and not just on the computer.

 

i would say trd is the quitest and injen probly the loudest i havent heared the borla or the magnaflow but if you want good sound clips of the injen check my cardomain

 

well borla, injen, and trd are axle backs so i would think magnaflow (cat back) would be louder (i could be completely wrong about that).

 

i have a borla cat back

magnaflow is still going to be the loudest.
the borla has a nice sound but its not incredibly loud..it still very well gets the point across.

 

custom and i love mine, i just wasnt going to pay all that money for a name, but the trd is the more quit of the list and injen being the loudest
