I agree Stillen or FastIntentions. Those are the only true dual exhausts that I have seen that have documented (by multiple dyno) NOT to lose anything down low and gain up top.

Did you guys see this HKS thread at my350z (apparently a whole bunch of exhausts here in the USA right now are from a very poor quality batch):

ever taken your G to the track? that's literally the only way you'll know if the exhaust helped you or not.

and as for your exhaust being fake, it aint. it's legit so don't stress over it. you're killing yourself lol

same thing with 20 in rims, certainly make your car look nicer, but makes way for a more sturdier, rougher ride.

i wouldnt want to go back to stock for sure!
wrong about the HKS exhaust. 20" rims do make your car slower, on the track

that's why HKS provides a 4 year warranty. HKS has dyno gains, (which are higher than both fast intentions and stillen).

HKS exhaust and............?

There are no real advantages to just an exhaust system. (except sound)
Unless you have a better intake and at least a 5/16" spacer you've almost
wasted your $! You've got to get more air into your intake so the exhaust
mod will be realized.......air in/exhaust out.

I haven't noticed using more gasoline. However, people do tend to drive a bit more agressively, for whatever reason(s) when these type of mods are installed . . . And as such, you will definitely use more fuel.
