please read and answer this for me

so i have the 2013 rs8.0 i notice a sweet little throat in my exhaust compared the to normal tc and to my 2011 tc..does it have a trd? it is release series you'de think they would do something cool like that but have no idea..if it isnt, what does the damn trd exhaust sound like? i hate the rice sound and lame honda rip you always hear i like those more subtle systems w out being to deep hopefully the trd is like that

as for an after market intake..im going back and forth between injen and k&n..but i got across a special weapon intake? dont know much about them i tried youtubeing them and the only thing was a tiny ___ 06 scion iq thing that got 4 hp more w like 5 pounds of torque but everything current says 6 hp w 5 pounds of torque..ik other variables play a part in the actual output yadda yadda but does special weapon just not hold up to what they claim? or are they maybe better than i think? maybe i should just stick w the injen
