Hks Silent Power Vs Kakimoto Regu 06&r

[Wogan]

Hi all,

I've been trying to decide between these 2 exhausts, but i haven't heard either in real life. Was wondering if anyone out there would be able to answer:

Which is quieter when granny driving?

Which sounds nicer when you fang it?

I've read a good review about the Kakimoto, but haven't heard a lot about the HKS.

Any info / opinions appreciated.

[nizmo_freek]

I am using HKS dump, HKS front pipe, no cat and hks silent high power catback and its rather loud when at full throttle, not to bad when cruising, and dosent drone at all when at 100kph, when the rest of the exhaust was standard and i had just the hks catback bolted on it was very very quiet! From what ive read the kakimoto is very quiet but still sounds nice when giving it some, check in my signature for vids if you want to hear what mine sounds like.

The HKS is what I have too. Like Jason said it doesn't drone, I'm happy with how it sounds all around. Wouldn't mind having a 'loud' switch from time to time though lol.

I have a TRUST Power Extreme 2 which is reasonably quiet, doesnt drone whatsoever and does have a real nice sound to it when on boost....

I also have a hi-fo cat and JJR split dump pipe.

i have apexi n1 evolution on r32

3.5 inch stainless was why i purchased it over the hks

I was looking at the GReddy/Trust PE II, heard it was quiet on idle but had a nice 'roar' to it when you give it some.. However I myself am going to go for a stainless Kakimoto N1 full mega, they are already made to comply below 93 db.. I'm going to get mine with a cannon silencer just to be extra sure...

Thankyou for your replies guys,

I will be installing it on an R32 gts-t with an rb25 turbo, the just jap split dump and xforce hi-flow cat, so i realise it won't be very quiet, but glad to hear you guys are getting good results. I'll check out those vids when i get home thanks nizmo_freek.

hey wogan, i was in your situation a long time ago.

personally i dont like the hks because its only a 3" cat back, where as the kakimoto is a 3.5" catback.

i would strongly recommend the 3.5 if u are planning some serious mods later on. if not then the hks is your exhaust.

because the way the hks is designed is it very very quiet on idle and cruising, but i must warn u its one of the exhausts that have the wet fart exhaust noise....rather then the deep growl a kaki has.

if you want a nice note wen u "fang it" id get the kaki

but at the same time the hks will not drone or get you into shit with the epa, being very below the db limit.

id go with the kaki personally, 3.5" exhaust = more hp + you get the cool titanium finish (JDM yo =D )

^^^ are you sure about that?

My understanding is the HKS is 120mm tip size and Pipe Size 85mm.

ie. 4.7" tip and 3.3" pipe. And it sure looks like that, hell if the piping was any bigger I'd be scraping 24-7.

its been a while but i remember the hks being 3" pipe and 5" tip where as the kaki was 3.5 pip and 6" tip.

or something close to that.....

[eddieeeee-ro]

pretty sure the HKS exhaust starts 3" from the cat back but gets bigger toward the end.. and finishes around 4.5"

[Wogan]

Just been doing some research, Seems the Kakimoto Regu 06&r is only 60mm in diameter at it's smallest point.. therefore it's only really a 2" exhaust.

Also the availability of the HKS Silent Power to suit a R32 GTS-T is pretty low. Might be able to get one from Nengun or somewhere, but i don't really feel like waiting till next year to install it.

The Kakimoto N1 is great, but it's a full system and i already have the split dump and high-flow cat..

Does anyone know of a reasonably quiet, quality 3" cat back system to fit an R32 GTS-T?

[Adz2332]

i have the Kakimoto Regu 06 on my GTR R 33 love it sounds great.. queit when you want it nice sound when accelerating hard

+1

id like mine to sit up high as possible for less scrapage.

[Wogan]

I should specify that the kakimoto regu 06&r is 60mm in diameter for a section on the R32 GTS-T exhaust.. possibly larger on other model cars.

Looking at possibly a Trust Power Extreme 2... off to research again

The only scraping problem generally comes from the resonator, so best take it off and you shouldn't have a problem

[Wogan]

Seems i was wrong about the kakimoto pipe.. the series ranges from 60 to 80mm, but the R32 gts-t one is 80mm.. guess i'll buy that

[Swink33]

I would recommend the Trust PE2. I think its a 80mm pipe. Reasonably quiet with good bark on command and a great note. I have never had any complaints by the police with it (including 3inch split dump + front + cat). Its also fairly cheap. I got mine from Autobarn and paid like $670 approx. No need to wait for it to be ordered in either.

Here here for the P.E.II.

I've got a Hks dump into blitz front pipe into X-force cat into P.E.II.

Sounds bloody great when pushed but minimal drone when cruising.

[rb2?]

cuz rb20 screams its nuts out at top end go for a 3.47'', it helps, ive got a trust 3.48 straight of my turbs, idles nice and is v.loud above 6000rpm
