Dyno numbers for HKS Hi-Power Ti???
 

I've been patient and I've searched..... cannot for the life of me find dynos for HKS Hi-Power Ti exhausts. I know AK installed this exhaust and only saw +1 HP from it, but the dyno was messed up.

Does anyone know what this thing is putting down to the wheels? I figured HKS would have put more time into marketing their product with dyno numbers.... or perhaps they didn't like the outcome? I don't know. But this is one sexy exhaust and sounds amazing too, but I need numbers! lol

Who has them?

Mine just came in yesterday...I plan on dynoing, but it will be with the G3 intakes and Berk HFCs installed as well. If the dyno wasn't an hour away, I'd definitely do independent dynos.

Sounds good because I'm going with Berk HFC's as well and I've already got the Stillen G3. Hopefully this setup doesn't throw a CEL.

Here is HKS with kinetix HFC on dyno. It makes 305

That looks like ilive2win's car. I don't believe he had a baseline dyno so it's impossible to say what gains he got after installing the exhaust unfortunately.

True but the final numbers are good :tup:.

Agreed :)

I don't have the chart laid over the stock at the moment but on mine (NISMO model) the HKS made a small gain all the way through over the factory NISMO exhaust (which already has the better section 1). Peak was 305.1 HP & 249.8 TQ at the wheels on a rainy day and on a Dynojet. Average was about 5 HP higher than the NISMO exhaust. Sound DB level was below 95 DB (for all states that comply with CA law on that). 98's dyno may be more apples to apples for you though.

Sounds very nice but not annoying in any way due to the sub silencers and looks aswesome. Tips are adjustable in lenght as well so it's nice for guys who are running the diffusers and rear skirts.

Hi i'm new here so i don't know what to say but i got a 370z 40th anniversary. I wanted to hook up the HKS Hi-Power Ti exhausts but i don't know the number's it puts out. Does anyone know how much hp and torque it puts out?

That is the whole point of this thread. It's the exact same answer I'm looking for. Stay tuned and I'm sure somebody will get those numbers in here eventually.

According to Import Parts Pro, the Nismo exhaust adds 5.4HP and you're saying you got approx 5HP more than stock Nismo, then it might be safe to say this is a 10-15HP exhaust??? I was hoping it would be more in the 15-20HP but I can live with 10-15HP increase.

It's a little difficult to gauge as the Nismo S-tune exhaust is different than the Nismo exhaust that comes with the Nismo edition 370Z. S-Tune uses a Y-pipe configuration whereas the Nismo edition OEM exhaust uses an H-pipe.

10-15hp is typically the normal gains expected for a catback though.

I just changed my exhaust from an F.I. with 12" resonators to the HKS and I noticed significant low and mid-range improvement with the butt dyno over the F.I.

does any one think magna-flow exhaust would be better then hks hi-power?

um...lol:icon18:
