To sum up the hp gain thing-
All axle-backs (which is this is one of) add 5-7 hp even on an IS350. They're all pretty much identical for the very minor power gains.
You can do a little better with a full exhaust that deletes the cats (or replaces em with aftermarkets) but it won't be legal. Those systems (which typically cost more in the $1200-1500 range just for parts) will add more like 10-15 hp on an IS350.

it's the most free-flowing exhaust. after the y-pipe, the two cylindrical canisters and big stainless steel tips are all business.
upside is, it probably makes a little bit more horsepower than the competition. but the gains are so marginal that they're almost negligible.
downside is, it is hands down the loudest axle-back application.
i got mine second-hand, so i don't know if $800 is a good deal...

Anyone who says they can "tell" the hp change from an intake is confusing noise with horsepower.
ALL axle-backs add 5-7 horsepower tops. No human can feel that little an improvement.
Intakes add 0-5 hp tops, so see above about feeling that.

I had change both F-Sport Intake and Fujitsubo Exhaust. The feeling of HP gain form original car is not much as my expected. But you will enjoy with the more bass sound from Exhaust and screaming sound from F-Sport Exhaust (@3,500 RPM and over).
It surely that change the Exhaust and Intake will make your car run a little bit better.
