Gday all

I am looking at getting a new exhaust system and I am wondering if anyone has used or got a HKS system off just jap, Main concern is how loud it will be?

Also what is the difference between the series 1 and 2 as they dont have any series 2 left,

I am looking at the HKS Hi-Power 409 Exhaust System, or maybe just go to a exhaust shop and get them to make one, any thoughts??

cheers

HKS do a Hi-Power silent exhaust that are reasonably quite due to there being an extra muffler

They have them at nengun.com heres the link http://www.nengun.com/hks/high-power-exhaust-silent

They can normally have the items to your door in under 2 weeks

I run one. They are rated at 92db

It is not too loud and does not drone.

I use to run a fujistabo legarus R (waht ever they are called) at 89db and was too quite. Hardly heard it

There is hardly any difference between series 1 and 2 exahust. I have had both on my car. Maybe one mount is slightly different, can't remember

The HKS Hi-Power Silent and the 409 are basically the same thing, just the silent is made from shinny 304 grade stainless and the 409 is made from exhaust grade 409 stainless. i think the main difference between S1 and S2 is the length.

i run a 409 system in my car, it has a middle muffler as well as the cannon tip. its not quite, but its not obnoxiously loud. my car is an auto and there is some drone in the cabin especially when travelling at 80-90kph that can get a little annoying when stuck at that speed limit for 1-2hrs. but its nothing the volume knob on the stereo doesn't fix.

how much are the 409's going for at the moment? might be cheeper to get one made up at an exhaust shop, at least then you can get a couple big mufflers put on it to get it really quite if you want. i must say though, the HKS exhaust is a quality made system and it really was as easy as bolting it on, all the hangers lined up, angles were perfect etc.

i got a hks silent on my s2, and it sounds really nice, no drone, no nothing, only thing i really really miss is the burble i used to get from only having resonators in my system. the muffler is a bit big so it kind of removes of the burble.

but i do say its heaps quiet, i tested mine with a db meter a while back and i got 87dB, that was with a 3"cat 200cell, and 3"bellmouth dump.

thing is, hks only has the preset tips for the exhaust, so no twin endpot or so. just the big oven pipe :)

also it would be very expensive to get a mandrel bent exhaust made in 3" 304 steel.

but then just choose 1 endpot and 1 resonator. sounds blooody sweet!!!

p.s if you want a vid and sound clip of the silent system, jut let me know

I am thinking of going the non silent one as i don't want to end up with listening to the fan belt rather then the engine again. The hks 409 is selling for $999 on just jap.

I am still waiting to hear back from just jap on eta of new stock so i might go around some exhaust shops the only problem is there isn't much choice down here in tas.

cheers for all your feed back

I have a spare stagea/skyline exhaust sitting at home if you wish to buy? 3" with rear twin tip stainless muffler. Came off the rb26, but as far as Im aware they should suit both 25 and 26 models. Not 100% sure though

Is the exhaust off a stag or skyline as the the skyline exhaust is 60mm shorter, just enough to be a pain, is it full stainless or just muffler and how much you looking for it??

Yeah it came off my S1 RS260 Stagea. I will admit it is mild steel I think, but a stainless muffler. I'll dig it out tonight and take a happy snap of it. I wouldn't want much for it mate. $200 would suit me. But just noticed you are in Tassie, so not sure what shipping would set ya back. I havnt gotten around to posting it up in the classifieds as yet.

I have a hks 409 exhaust, high flow cat, greddy front pipe and hks split dump. Good flow, fck all drone and hangers line up perfectly. Change your O2 sensor while your at it. IMO dont go for full stainless as it doesnt bend if the fitting is out a bit and dont buy a dump/front pipe bcos you can just replace the front pipe if you bottem out on kerbz and shit. Flex front pipes are decent for that. JDM stuff has the best gaskets and fitting.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
