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.

      Duncan's V37.......race car?

      By MBS206 · Posted

      Something I meant to say when we were chatting the other night about having an open trailer floor being great to work on a car, but you've never used the feature... It's a great place to park a car after doing suspension component changes, and do the tightening of all the bushes with the car sitting at full ride height. Especially when you don't have a 4 post hoist!

      That is way more science than even I would use. I just eyeball it, not even accounting for the non-verticality of the tape measure when held on the lip and the centre at the same time. +/- 2mm is good enough for the girls I go out with.

      By Duncan · Posted

      So, before putting them in I need to understand the stock ride height. This is how I measured it: First, check the diameter of the wheel's centre cap, it was 52mm. Then put a piece of masking tape approximately across the centre and measure 27mm (half) from at least 3 sides to get a reasonable idea of the centre of the wheel cap. Mark that with a horizontal line as one measuring point. Then, directly above the wheel on the guard, put another piece of masking tape in approximately the centre. Use a string line to find out the point on the guard above the centre of the wheel cap and mark that. Then it is simple, just a tape measure to check the distance from centre of the wheel to the centre of the guard. Final results where  LF: 381mm RF: 379mm LR: 401mm RR: 400mm Pretty even considering they are 120,000klm old factory springs, lets call that 380 front and 400 rear.

      By Duncan · Posted

      So....knowing that I have a problem with power steering temps on track and another Wakefield day booked in next Friday, I've done the obvious thing They are very reasonably priced at $1650, considering they are a big monotube shock, double height adjustable (don't have to change pre-load to change ride height), one way adjustable damping and standard sized and customisable springs if you want something other than what comes with them. They come with 9kg/mm front and 4.5kg/mm front and I went with that as a starting point because I'll add adjustable sway bars too https://justjap.com/products/bc-racing-coilover-kit-ds-ds-infiniti-q50-v37-14-current#description Unfortunately they didn't come with rear strut tops so I've re-used the factory ones which was a bit of a pain. Also, the adjuster for the rear shock will be an absolute nightmare to get at, and while there are extensions in the kit I can't see any way you can actually attach or use them

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By Duncan · Posted

      I also had 2 bulbs blow at once, years ago in the stagea. made for a fun drive home. The issue was the voltage regulator had failed in the alternator and it was giving 15+ volts. Really, I was lucky all that was fried were the headlight bulbs. So, I'd suggest you check the voltage across your battery terminals with the car running and warmed up. Yes, you will need a multimeter to do so, sorry.
