Yeah thats the thread that scared me lol... I'm gonna try them out anyways, Semtex, when he just had those two, said there wasn't any drone and at cruising, it was very quiet so I guess what might seem too loud for some might be quiet for others (all depends on preferance and possibly age... lol).
I want mine to make a noise throughout the range but be quiet when I'm not revving, both of these exhausts on their own will be relatively fine, however the stillen is quieter (this is and isn't a good thing for some). From the videos and bezzitas car, the fi's have a deeper tone, but keep in mind the car had high flow cats too (the stillen with cats give a deeper tone aswell). Actually GTRFAN went for a drive in the car I didnt speak to him about it but he could give some insight on the FI stuff (the car has FI cat back and FI hfc's)
Darren?
as for the stillen I have only heard it on videos, so I cant say if it'll be overly loud with the cats, it is difficult to tell because cameras can either add or remove noise......
Possibly this Friday I may be able to let you guys know if I can get mine booked in that is....
End of the day you'll be happy with either. If you want a visible exhaust go the FI if you want it more stealth go the Stillen. Stillen/berk hfc combo give good gains, not sure about the FI stuff with gains though, Any QLD guys who have installed them here?
maybe post the gains below (there is another thread on this I know :P)
I think (dont hold me to this) semtex and another member got 28rwkw and 27rwkw respectively with the stillen cat back and berk hfc's
FI guys post below haha
