Just installed the trust extreme exhaust and got my approval cert from vicom. Anyone else installed this? I would like to know what your comments are on this. For me, I must say it sounds quite aggresive, especially in the cte tunnel with the reverberating effect and echo. Cons is that it makes me want to drive more aggresively as well

I feel a quite a substantial change in performance but then again as i discussed with Ivan it might be entirely in my mind. The sound probably makes me think im goin faster. Now im looking for an equally aggresive sounding air intake to go with it. Welcome any suggestions.

Oh ya, what other mods can i do for the exhaust? Change the manifold?

I was about to ask if anyone had install it and what is the difference between knight sports and trust one. I am comtemplating either.

Hi all,

With all the chatter about exhaust and the ever-expanding range as well, just wanna get some additional info and tech knowledge from you guys.

Currently, for most of the zorst that U guys have installed, are they 2.5" or 3" in sizing?

Been researching into the US scene and their proiducts as well, other than the 1 or 2 companies/brands in Japan that specializes in rotaries, the Yankees seem to be the next better option and their products.

But somehow exchanged and called a couple of them, and it seems like just for NA without aftermarket force induction systems, alot of their zorst are 3" in sizing compared to the Japs of 2.5", if I am not wrong.

Any assistance in this guys?? I am still contemplating what zorst to get, and is there a difference for a zorst meant for manual and auto RX8?


Cheers

Yo dude, is it true it's really 6.1kg? I'm also thinking of getting this exhaust since it's approved. Also, is it loud on low rpms?

I've got the Blitz sus power intake and it's sounds really aggresive. The plus side of this intake is you don't have to change the filter as it's made of metal.

May i know how much did you paid for the titanium exhaust?? Where did you get it??

EBS

HI

Pse share details. Mi very very interested!!!!!

Emperor

Whats the total damage including getting approval?

I think the price is 1950 for our RX-8 if I am not wrong... maybe Fong Kim have it... but I guess is for the manual version only... "auto" fix liao no effect at all except sound I guess...

lennon

Actually aftermarket exhaust helps in reducing restriction and give a better high end response..... Even thou the dyno shows not much gains, it's the feel and throttle response that gives satisfaction...... Many poeple look into HP gains, which is unrealistic to me....

If anyone is interested in performance results, please contact me BEFORE you install any exhaust to get a base run so that you can compare the performance results after the installation. Just a point to note, just changing the muffler alone is not going to give huge gains so don't get your hopes too high. You can expect about 2-3HP peak RPM max improvement. To get more out of the exhaust system, the only way is to go all the way from head(er) to (dophin)tail and any animal in between.

Hi Lennon, yes I agree with what U say... the power gains is not a lot unless U have done internal mods + exhaust but the amount is not small... anyway, I do love this exhaust la cause of the titanium tip... sounds foolish right to pay so much just for the tip... anyway, I do have a exhaust which is good for auto RX-8s [recommend by coupe07] and really, the sound simply just blow me off the ears...

derekwcw

So what exhaust is recommended for an auto my fren?

I need to source one out for my auto ride

lennon

You're saying RE-Amemiya.....

ngkenny

WHAT ABOUT ME????????

guys...on a serious note....muffler alone will not have a lot of gains. You will have a nicer tone...and of cos that backfire sound when you rev a lil (that sound alone got flyer and me so excited). Please don't expect miracles to happen cos it will not happen. Marginal gains for now until my brother and me change the header and ***** cat. Thats where we should expect more.

I don't know about other brands (i am using knight sports)...but i assume its all the same for muffler alone.

tan280

R.E Amemiya exhaust... tested and verified gain... can ask coupe07 abt it if U are interested...

coupe07

i'm changing to re amemiya exhaust liao..... letting go my knight sports exhaust

RE - is it LTA approved?

EBS

Hi guys

This is getting more interesting and offer more choices. Can we consolidate a little to benefit everyone??

1. Fujitsubo - LTA approved
2. HKS - Failed
3. Knight sports - (LTA approved or pending approval?)
4. Re Amemiya - (LTA approved or pending approval?)
5. Greddy MX mufflers (??) - LTA approved
6.
7.

If possible can put price so its easy for others considering these brands.

LTA approved means with cert from LTA and can show TP. Tink inspection fee is $52.50 (incl GST).

tks for help fellow bros hehe

sqflyer

EBS bro... there are basically two forms of LTA approval for exhausts, one is for commercial resale and the other is for personal use. Knights Sports exhaust can be approved for personal use, RE Amemiya should be too but I'm not sure (ask coupe07). I think Fujitsubo is approved for commercial resale and not sure about the Trust Power Extreme. Confusing?

Hi

I know from previous car and current owners of after mkt exos (other made) that u need the LTA approved cert ($52.50 at approved inspection center) for after mkt exos system. That is the one they take photos and kept in their data base. When TP stop u, u show them the cert with ur car chassis as well as the brand of exos with the Jasma cert number from LTA (thru their approved inspection centre).

Maybe this is the commercial resale version (Fujitsubo?). What is this 'personal' use process? Does it mean we can get hold of ANY brand as long as they have JASMA for personal use?? Then thats good news indeed!! Can Ivan comment??
Tks

EBS

Hi

Just checked Greddy japan website. They dont have application for RX 8 for Power Extreme II mufflers! The closest is their MX (maximum and extreme) mufflers so maybe bro style can comment which is the exact exhaust he fitted and is that a full cat-back exhaust or just the mufflers.

Tks

EBS

Bro style

Get the Re Amemiya intake box and the header to complete your transformation !

Whichever type of LTA approved exhaust (commercial resale or personal use), both need to go through the $52.50 VICOM inspection and stamp on the exhaust certificate. What I'm talking about is the LTA approval process. For an exhaust to be LTA approved, it needs to go through LTA's process which is quite troublesome especially for the commercial resale type of approval.

For personal use approval process, coupe07 is the best person to relate his experience. But generally speaking, you can get any exhaust you like as long as it is made specifically for the make and model of your car and is able to pass the emissions and noise level tests as dictated by LTA. You would have to get the manufacturer to provide you with letters and certificates to prove that it was made for your car and pass the required emissions and noise levels and also an invoice. Write a letter to LTA to apply for their approval and send all the documentation, go for LTA and VICOM inspection and once all the "i"s are dotted and "t"s are crossed, then you get a stamp on your exhaust certificate to show TPs when you get pulled over. Yes, it's good news, but you have to jump through all the hoops and do a dog and pony show before LTA legalises your exhaust.

go for full 3" midpipe with metal Cat, that where the real gain is, but some MM 8 might get CEL after some time, K.S. just released one with metal Cat. but piping 60mm(2.36" < OEM 2.5Inch) ?, RE 2.5" but don't look like they use Metal Cat, same as Rmagic , might not produce any CEL as they r conservative as RE & Rmagic come with JVIA cert. but what ever brand u get i don't think it can pass LTA, anyone trying ? I had tried 2.5" custom made at ManExh & changed to 3" later, don't waste time on anything below 3", i had spend my $ to learn, search & read thread regarding TurboXs race Exh.; header check with Alvin he have it, gain ?

EBS

Hmm interesting. The 2nd half where u write a letter has been done by some of my friends (for other made). They were able to get their exhaust approved. The reason is these same exhaust were prior approved before. The FIRST piece is the most difficult, and if I am not wrong, require a JVIA cert (which itself certify the said exhaust is for the specific car and pass the emission and sound standard in Japan).

So going by the process described, can I safely say that

1. Knight sport exhaust is already approved by LTA (ie the owner has the cert and paid $52.50 inspection fee) for personal use?

2. Re amemiya has approval for personal use as well (??) or pending?

Can the owners confirm this??
