Hi!
I'm new to the Forum and, i know it sound like a typical noob question ....
How high is the sound level of the HKS HI-Power exhaust(in db)

I live in Germany and the Law doesn't accept to loud exhausts...

I know that HKS offers a silent version of it but i just wanna know....

if u want silent exhaust, then get apexi WS

pReave · 06-21-2006, 04:21 PM

Oh and i forgot i drive a Sr20det powered S14..

Thx for your Help Allen... do you have some soundfiles? Would be great if you find some.

The RS*R Ex-Mag exhaust is quiet.

The Blitz Realize TT exhaust is also very quiet.

Now there's the Circuit Sport Dual Tip exhaust that's also 3" piping and utilize a stock looking muffler set up.

Those exhausts coupled with a hi-flow cat and you'll only lose like 5 to 10 rwhp at the most and still have the flow of the 3" exhausts, but only like 40% of the noise.

fujitsubo has nice quiet exhaust systems, i would look into those if you can get them there

mmdb · 06-22-2006, 12:54 AM

Invidia is pretty damn quiet... almost silent.

pReave · 06-22-2006, 04:46 AM

Wow thx for all the Help guys!

I saw some Blitz Nur Spec R Exhaust on S14s... that Bitch is loud as Hell...
Thx again to all, but i don't really like the design of the Exhausts that you guys suggested.

I just want to know how high the sound level of the Hi-Power is, if it's to load i'm gonna get the silent Hi-Power.

i have the 65mm Hi-Power on my s13.
i dont know in db how loud it is,
but in my opinion, its not that loud until you really start to push it.
its just real nice and deep most of the time.
im sure theres quiter exhausts out there but i agree with you that the HKS hi-power looks alot better than most.

If you have the silencer for the Hi-power I would suggest to use that for noise concerns. With the silencer in it is almost quiet as a stock exhaust!

mmdb · 06-22-2006, 08:31 AM

HKS hi-power isn't loud in my opinion. It has a nice smooth deep tone to it. Check on streetfire.com. They have a few video clips of it. Good luck.

OdessaS13 · 06-22-2006, 10:41 AM

check out the espelir jgt500, ive heard very nice thing about it and not a lot of people have them

articdragon192 · 06-22-2006, 11:52 AM

+1 for the RSR Exmag, not the Exmag GTII though. It's so quite.

trsilvias13 · 06-22-2006, 12:55 PM

"loud" to some people is actually pretty quiet. Get something that your can unbolt and switch muffler for track and one for street. That what I going to do with my N1.

Thats the turbo version on my 1992 240sx, its not very loud, compaired to some exhausts, btw im still N/A so im sure it will be much quiter on an SR20.

pReave · 06-22-2006, 03:15 PM

That's what i wanted to know. Thx again to all! I think im gonna get the Hi-Power.

punxva · 06-22-2006, 03:42 PM

great choice, i know when i was deciding if i wanted it or not, i couldnt find a clip, so i said that once i got mine i'd make a clip so everyone could hear just how it sounds
