Ive been through through alot of exhaust on my 5AT

Nismo= No drone
Nismo + HFC = TINY bit of drone
Nismo + Testpipes = OMG I cant hear, soudns terrible
Greddy EVO2 = Slight drone but barely noticeable
Greddy EVO2 + testpipes = More drone and a terrible rasp
Stillen True Dual = No drone
Stillen True dual + HFC = No drone ( No rasp either)
Stillen True Dual + Test pipes = No drone and no rasp, just sounds good.
Apexi EX-TI Titanium single = OMFG THE DRONE

 

good post because i have the fast intentions and turboxs test pipes and the drone around 2k rpm is annoying at times
