Hks Hi Power Silent Or Kakimoto Regu

[R.3.2.G.T.R]

yup i went the same route and picked up a kaki regu and installed it myself.. love the sound

[vudoo]

wat kind of power gains will i notice if im chucking this on, plus catco high flow cat (the 175 dollar version from just jap) and belmouth front/dump pipe (couldn't find a split pipe for r34gtt for some reason?)

everything else is stock, stock boost - no boost controller yet

[vudoo]

got it baby!

i was looking at then getting these two items to complete the exhaust:

http://justjap.com/store/product.php?produ...=276&page=1

wat do you guys reckon? remember this is just for street, i don't want nothing crazy crazy, as u can tell im just at the beginner stages of doin minor mods to my street vehicle

there is an xforce stainless steel cat for the same price as the catco one but i herd catco is a more reliable brand so yeh...

is there any disadvantage to getting the belmouth front/dump pipe over a split style verson front/dump pipe? couldn't find one that was for r34gtts...

[gotRICE?]

The only adcantage the bellmouth has, is that they dont make splits for R34's

Personally, from experience i would stay away from the split type anyway. No end of trouble with boost creep, had to mod the wastegate pipe to clear the wastegate flapper, then removing the thing was a 6 hour exercise with a blow torch. Destroyed my 02 sensor thread too. Wouldnt risk it again!

Have seen a few of the bellmouth ones. They seem to work great.

have the HKS Silent Hi-Power and JJR dump on my GTT. Love it. You won't get a deep burble around town like it's a rexxy but it's also almost legal and not over the top at all (rated at 92dB)

as for power ... it all depends really, i'd say 10-20rwkw extra with no other mods as it flows much better than the stock system

Good choice on going to Kakimoto, I had the HKS Hi Power on my GT-R and it was just too quiet.

Blitz Nur Spec R FTW! I teamed this up with a JJR bellmouth front/dump and a catco hiflow cat and couldn't be happier Great looking exhaust and the sound is hawt. I have no mechanical experience and I didn't have too much trouble installing the system myself. Useful hint though, get yourself a socket set (1/2in or 3/8in driver if you don't have one already), lots of WD40 and a 6 pack, coz those dump nuts are a c to get off lol.

hey if anyone in syd wants to trade a blitz nur spec R for a HKS silent hipower let me know ..I could use a change (the HKS costs $200 more at JJ btw!) ...cat-back only

[SiR_RB]

How does everyone go with the kakimoto regu on the street? Any problems with noise just driving normal?

[boostn0199]

If ur number one objective is queit than yes the kakimato but be warned they have a 2.5inch welded in restrictor in d cannon so yeah if you want performance first i wouldnt buy it. I regret buying it as i ended up cutting the restrictor out as was losing piwer and after that no longer quiet.

[SiR_RB]

They come with a restrictor in the cannon from the factory ??

I never knew that !

Since I upgraded my turbo and cat, my HKS Silent Power is so much louder. I love this exhaust to bits, the way it sound the growl is like the angriest tiger you will ever hear. At idle/cruising in 5th sure it might be legal but lol there is no way in f**k stick this exhaust is legal at stand still with a rev. I would have went HKS, Ive heard both exhausts and prefer HKS. Ive also got the JJR bellmouth dump.

As for installing your self, yeah I wouldn't pay someone to do this job.

HKS has a little hot dog thing in the middle.

That cat is good but its ceramic. You've spent a fair penny on a brand new exhaust, may as well get a metalcat or even a venom metal cat. Ive got the venom 5" body 100cpsi cat on my car. Shall see how it goes when I get the car back.

[SiR_RB]

I'm running -7 turbos, r34 gtr dump pipes/stainless front pipes/3" decat

Just deciding between the hks silent and kaki regu.

I must admit the hi power silent at wide open throttle sounds Porn ! But I realy do love the look of the kaki regu and build quality, plus the pipes are straighter which should give more power..

Yeah no one does know it until you accidently stumble across it or see pics. I had a thread somewhere showing all the pics of it and how I removed it etc so in my opinion the kaki regu 06 is just a cheap lie in regards to good flowing exhuast with minimal noise when as a matter a fact its just that welded in silencer thats doing all the sound reduction, but in saying that once you take the restrictor out its a great exhuast flow wise and sounds great even though it probably isnt the queit exhuast you would expect now. So what I learned was there is no cheap way of high flowing exhuast while being quiet unless your going to go for $3000 system like racepace will make.

I got the Kakimoto Regu on my GT-R and I love it. Barely hear the thing idle but cruising alone it sounds fantastic. Get it through Jesse Streeter and save yourself $400 from JustJap.

Theres 2 types of HKS HI-Power Silent...

1 = Mild steel with big resonator, stainless cannon (quiet)

2 = Stainless steel with hotdog resonator, stainless cannon (fairly audible)

In any case, I went custom cause I got the sound I level I was after..

[SiR_RB]

J-Rad does your Kak regu have the silencer in the cannon? or did you remove it?

10-4, the one on the justjap website is the 95mm stainless one, and it has a big oval resonator and cannon at back?

[Deano 1]

i got a kaki regu on my car, make over 300kw with it so not restriction so far. see how it gose when i put my -5s on. i dont think my cannon has a silencer in it.....

i really think the sounds of your exhaust also comes down to your cams, dumps, and front pipes aswell... the sounds change quite abit when changing these items, so somtime you mite here someones car and think it sounds awesome...... so you think you can just go buy the same catback and bam youll have the same... most of the time thats not the case... just a heads up

I guess so? I never removed anything out of mine.
