Some awesome new products coming out for the FT86 and the BRZ

The first exhaust fits the diffuser really well! But, goddamn, it looks a bit too big in these pics...

124mm= 4.88 in. Which is way too freakin' big...

The second one's 3.7in is much more reasonable...

Unless, these aren't in mm....

Ill wait for the dyno results :popcorn:

Guff its in mm, and it pretty much shows in the pictures .... yes it does look way too big. Amuse exhaust looks perfect, though I'd be concerned about the drone during cruising

The High Power Spec L sounds very interesting with its claims to reduce backpressure by 60% and at half the weight also. Apparently conforms to Japanese noise requirements too. Wonder if that's the same/similar to Australian requirements?

Need video clips on how these exhausts sound.

Was looking for exhaust clips and found this. Not really related but I think I'm laughing more at the guys laugh at the end of the clip LOL

Is that before s/c or after?

Or do they have more then 1.

That first exhaust tips are crazy. LOL

It's not. The testing procedure is the same but Japanese regulations allow louder cars (96dB vs 90dB in stationary tests).

I like the second one, but damn it'll probably be pricey...

Thanks for clarifying. If it's about 96 db that's going to attract too much attention but to be honest I wouldn't care. If the cops defect me I'll just put the stock exhaust back on and get the canary cleared.

That's as long as there's no annoying drone and I'm still driving around in a nearly stock 86 :happy0180:

Bags getting the HiPower exhaust!

Heard the Hi Power and sounds much nicer than the Legamax. Will probably be the exhaust I'd go with at this point in time. Haven't had much chance to see/hear what else is out there.

The Legamax is just an axleback, so performance gains are negligible.
I'd like to know if the muffler has chambers or is a free-flowing drilled pipe design.

The % of backpressure reduction is not a very useful value, as it changes with the rpm you'd need to know how it changes. If you have that 60% reduction at 3000 rpm you won't have any torque left.
I guess the Hi-Power is for FI engines.

The only think that is interesting is the use of the Helmotz resonator in the Hi-Power system.

The Y-pipe of the Hipower send the pipes almost backward, with very tight corners.

I haven't seen a very clear picture of the car from below but I think there's a better way to do the separation of the flow between left and right.

Where are the HKS parts manifactured?

The legalmax comes with both catback and axleback.

Hey mate

You are right in saying this exhaust has been designed mainly FI more specifically for their new GT Supercharger kit however will work fine on a NA engine as for the y piece it is a very similar designed to that used on the R35 GTR exhaust that they developed some years ago now. Finally all there exhaust are manufactured in house in Japan.

hope this answers some of your questions

Some more really cool products from the weekends HKS Premium day at Fuji Speedway. Was lucky enough to attend for the 3rd year running.

How much power will the supercharger make!?

and how hard would it be to make more from it?

Helmotz Resonator. Interesting...so that's what it's called. Learn something new everyday!

I noticed that the y pipe was very sharp angled. I suppose moving high HP applications it probably would become and issue but for BPU I'm sure it would suffice.

The supercharged drift car from HKS is making 400PS...

It's not unusual for SC'd cars to make around 70 HP and T'd cars to make 100 HP above stock so...

HKS managed to squeeze out 200 HP out of their Supercharged FA20. Mind you, they likely changed everything else too... (And lowered compression!)

Well, I was talking about "streetable" mods. Of course, it they went all be damned a lot more is possible, but how good it will be as a DD is pretty obvious. For me, I'd think that 40 - 60 HP increase for SC & T'd would be a good increase for a car that will double as a DD and part-time track car.

Oh yeah! I agree. Getting 230 WHP out of this car would be excellent!

forgive my feeble and limited knowledge of these things but is the fisrt pic of post #18 extractors? :o

correct.

Interesting...why two different design if you're going to couple the same cylinders? maybe it's hard to tell from the pictures but they are two different diameters? The one on the bottom seems slighly bigger.

I'd guess you'd need a manifold for NA cars and a different one for FI cars.

I'd go for a bigger stepped 4-into-1 manifold for track car, both NA and FI, to maximise the top end power above 4000 rpm.

They don't seem to be much different from the stock manifold, exept for the absence of the 1st cat.

What's written in the sign?

Lucky a top level D1 car isn't used as a daily, huh? ;)

The extractors look awesome, but I would like to know how much gain you'd get from them.. Cams and high compression pistons are awesome things that interest me..........

At 12.5-1cr from factory Nafe do you think higher compression will help or be cost effective.

Maybe with monster cams it might but i cant see it being beneficial to the masses.

Would it help produce more power - yes.
Would it be alot - on it's own - unlikely
Will it be cost effective - not really, but no one claimed it to be. High power natro engine builds rarely are. I know this from experience in my old ae86.
Re monster cams - lucky HKS appear to have that covered as well ;)
Re the masses - that is for the individual to decide. You may be surprised how many people, particularly in Japan, would like to do a bit of n/a tuning... If people didn't want to do n/a tuning there wouldn't be so many modified n/a ae86's running around.
Personally I would sooner throw in some cams, throw on some really good extractors and bump the compression than turbo the thing.
Do I think that would produce more power than forced induction? VERY unlikely, but then do I care about out right power? Not really, or I wouldn't be looking at this car :)
Each to their own I guess :)

Hi gtauto,

Are you guys HKS distributors? If so, would you have any idea what kind of price would we be looking at for the full exhaust and coil-over suspension?

Cheers

These prices are APPROXIMATE only :

HKS LEGAMAX (mid pipe, rear muffler) $2400
HKS Hi Power Spec L (mid pipe, twin mufflers) $2200
HKS MAX4GT Suspension $3600

Go to bottom of this page and u will see HKS development and release dates/under development.........

pricey....thankfully im going straight pipe lol ;) but thanks for the pricing~!!

No probs, Bear in mind that HKS exhaust are 100% noise and emission legal in Japan which unfortunatly adds to the design and material costs.

cheers

gtauto any pricing on supercharger?

will you be getting you're own car right away?

Hey guys we are happy to announce that we officially have the HKS 86 exhaust in stock now, so now that Toyota has kept there end of the pricing bargain! Time to start modifying!

Cheers

Ps please remember to come visit our trade stand at WTAC for some exciting FT86 stuff.

you guys open on Saturday?

thanks

Hey guys here are some photos of the exhaust we now have in stock, Its awesome to have these in stock before the car is on the streets. We will be in on Saturday till 12pm if anyone in brisbane is keen for a look. Plus we have a confirmation on pricing which is a fair bit cheaper than previously mentioned.
