Induction definately, exhaust, I gotta say, I think yours has the edge right now. Although when it comes to driving comfort, I beat both of you - mine doesn't make a sound! (...for now <_<) BTW Scott, if you happen to come across a wrecker locally with a broken Aurion, let me know coz theres a few bits I might wanna grab while you're at it. induction sounds feral on Scott's car. hoping this doesnt change the note of my car for the worse but i doubt it will. need to get on to ordering that thing. I got to work today and had to ask what date it was to chnage my calender over. sure it's the 19th lol go to "find-a-part and put in a request for whatever parts you want.Although I have done this, I have only got one reply from a mainland wrecker saying he didnt have anything.
