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

got it baby!

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...

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

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 :P 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.

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.

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.

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..

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

I never knew that !

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.

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..

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?

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.

    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
