Hey guys, I'm quite new to the forum so forgive me if this was asked already. I'm in NYC, USA and was looking for a new performance exhuast option for my R34 GTT (Know of any other better options, please say!)

I stumbled on to the HKS HiPower and the HKS Slient HiPower. Does anyone know what is the exact mechanical difference? In your opinions, which sound better? The description of the two didn't help much, and low quality YouTube videos niether.

Also, if I want to get a exhuast silencer...would it make sense to install on the HKS Slient HiPower Exhuast? I feel the Silent version still has some strong sound from it, Or is it me?

How much power are you chasing?

Most Japanese systems need to meet the Jasma standard, which makes them very quiet, and usually flow less. Quite often there is a 70mm or 60mm restrictor inside the rear muffler which can be cut out with a die grinder cut off wheel if you want a bit more noise or flow.

I have the Silent HiPower on my GT-t and it's great. The difference between the two is that there is a second muffler added to the silent version just after the cat. For me it seems to kill any drone on the highway and makes the idle nice and quiet.

If you like in an apartment block or similar where your neighbours are quite close I'd recommend it, as its much quieter than other systems I've used

I was going to add a bigger turbo to hit +400HP. But how much would that change a exhuast sound? Louder or deeper/agreasive sound.

I tend to like exhuast sounds that are deeper (not lower just stronger sounding).

So check this. As soon as you put a 3 or 4" dump on that turbo your exhaust is going to sound worlds apart. It will be louder and aggressive.

Couple that with a hks whatever canon exhaust will be pretty loud I reckon.

Google the shit out of the exhausts you are looking at and check what people say.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      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
