I might be a close second
:
1) Fabspeed secondary cat delete w/ stock exhaust: Sounded like an M5/M6 and had no drone at all
2) Fabspeed secondary cat delete w/ Vorsteiner exhaust: fitment sucked, but sounded okay...no drone.
3) Fabspeed secondary cat delete w/ AA exhaust: nice quality, sounded good down low, but lacking up top.
4) Fabspeed secondary cat delete w/ Gintani exhaust: great sound, lots of compliments, but droned a bit too much.
5) Encore Innovation HFC's & x-pipe w/ stock exhaust: sounded absolutely horrible, way to raspy.
6) Encore Innovation HFC's & x-pipe w/ Agency Power exhaust: sounded great, really aggressive with little to no drone.
7) Encore Innovation HFC's & x-pipe w/ Remus Sport & Eisen connecting pipes: TBD
