now ur talking, because it seems thats all they did.
and its titanium for what, braging rights? what is your car going to be subject to 3000+ degrees? your exhaust will survive but the rest of your car wont. or maybe u want and exhaust system that wont yeild? just incase u know, it wont because u have a higher modulus of elasticity than my exhaust.

 

This guy. That exhaust is a work of art. Fujitsubo makes their exhaust not to be loud but give a nice power gain.

 

= sarcasm

I am sure that Fujitsubo did not ignore fluid dynamics and I would even venture to say that they know a hell of a lot more about it than anybody on this forum. It is a great looking exhaust and I'm sure engineered very well.

 

Titanium is lighter, but stronger - that's the benefit.
There are so many ways to design an exhaust, they don't all have to be straight through and 3". This one looks like it could offer the build quality, lightweightness of the GReddy Ti, but not be as noisy. It may not flow as good, but then I guess he might have to settle for a 600whp car as opposed to an 800whp. Sounds like a fair trade off to me.

 

Just thought I'd add to this:

There is now one more type of exhaust for the Evo from Fujitsubo. Well, since 05/19 anyway.

It's called RM-01S rather than RM-01A

The 'S' is a hybrid stainless and Ti. Price in Japan is 120,000JPY or thereabouts. Weighs 10.1kg, 2 resonators (thin ones) and one end can. The only two out are for the '05Sti and Evo IX.

Compared to the RM-01A type Ti, full Ti cat-back costs around 180,000JPY in Japan (for the VIII) and weighs 6.7kg.

The RM-01A in stainless is around 75,000JPY and is around 11.3kg

All three are 3" piping and have two thin resonators and one cylindrical end can.

I leave it to you so to which version is worth your money, but I'd say that if you want Ti, go for it. $ for $, it doesn't make an awful lot of sense, but when does modding your car has to make sense?

 

You are right i dont know the first things about fluid dynamics...but i have to tell you i am soo glad that you have come into this thread to bless us on this very subject, because you know i really wanted to know about that i was just waiting for someone to bring it up in a thread for no damn reason. I am pretty sure if the guy went with buschur or something you would not have ever made these comments you would of said " buschur top notch, only the best" blah blah blah". It might not flow as good as the buschur or some other exhaust but it will still make pretty good power...again though jdm exhaust are engineered alittle differently than domestic exhausts. Again i am glad you want to share your opinion on whats a good engineered exhaust and whats not, but thats all it is in the end an OPINION and we dont care so go start a thread about it or something.

 

isnt that the whole damn reason for buying an aftermarket exhaust? espically spending the kind of money he spent. if u guys can actually justify spending that kind of cash on an exhaust that will not perform as well as others that are 1/4 of the cost, then obveiously power is not your first pirority. listen, never did i say that it wasnt a nice exhaust, just not worth the money.

 

Gotta agree with this guy. And I do understand a thing or two about fluid dynamics. But Buschur exhausts are designed for performance first. These fujitsubos seem to focus on sound as much as performance. If my goal is 25 whp with an exhaust and the quiet one with a downpipe + testpipe makes 26 whp but the buschur "catback" makes 30 whp, ummm sorry, i think i'll take the quiet way out.

 

^ Well thats when the personal preference comes in man...not everyone on here goes to the dragstrips or roadraces or cares about dyno numbers, because in the end thats all we are comparing are dyno numbers so people can have braging rights on their exhaust making more power over some other brand etc. You are right i would not pay that much for an exhaust when i can get one for half price and make pretty much the same if not alittle more power. Its justified by the orignal poster thats what he wanted and he had the money to get it...its not only about power but the looks and style even though that may sound dumb to some people those are the factors for some others when choosing an exhaust.

 

i could go on all day with these stupid posts.
tbplayer45- u must be right, thats y they manufactured an exhaust that creates tubulance.

GPTourer- i didnt know u needed a super strong exhaust. and where exactly are u comming up with these ludacris 600-800whp numbers.

and as for sound reasons, thats y there are different types of mufflers. there is no reason to subject flow for sound. in fact creating the turbulance might sound funny.

 

 

wow, so much arguing over my frickin exhaust!!!! everyone is entitled to their own opinion...it doesn't bother me. i'm happy with my choice. yeah, it was expensive and yeah, i may have left 5-10 hp on the table, but it kept the sound level near-stock while STILL managing to gain some power and drop about 20 lbs from the car.

btw, i agree with whomever said fujitsubo designs for low end torque/streetability rather than peak HP. that is exactly how it feels. my IX's low end is MUCH better now. top end is probably just a little better. things may change when i get my DP and test pipe.

 

Dude great exhuast These guys in japan have been designing and building aftermarket parts for the Evo for over a decade now, they know exactly what they are doing and how they want the exhaust to perform and sound.

Post up some pics soonest, i want see how the exhaust looks on the car, and sound clips if possible

 

I have the RM01A SS and it's a great exhaust. Probably doesn't make that last three hp that a Buschur exhaust would but I'll take a quiet exhaust over a loud one any day! I purchased mine from KamiSpeed in Orlando and I too had to slip it between the seats and stick one end out the open back window. But it works! Had to drive 3.5 hours home that way sigh...KamiSpeed had another Fujitsubo Ti version there with just one resonator. A real work of art. The piping may have been larger than 3" diameter too. It "looked" as though it would have been a louder muffler and I believe the price was around $1600. When you delete the cat, it doesn't get much louder either. With the stock cat in place, there was only a hair's difference in sound level but the sound quality did change.

 

jason, i'll try to post some pix before i leave for vegas on saturday. sound clips too if i can figure out how to do it.

mr stock, how much louder does it get with a DP & test pipe?

p.s. the 1 resonator Ti exhaust is the "super-ti", not the rm01a. http://www.fujitsubo.co.jp/mc-prod/
