Exhaust sounds...; Choosing the right system

First of all, check out this short video clip...

http://www.youtube.com/watch?v=KkY19r5InAc&feature=related

Secondly, what kind of system would get a sound close to that... :D :P

I absolutely love that noise, but a lot of exhausts seem to be too deep and boomy. I love the high rasp of that system on the DC5...sounds like some Italian exotica!

Don't get me wrong, I do like the deep rumbles of the Impreza's etc. but nothing beats that sound in the video. B)

Is there a particular shape/size of backbox that will 'cause the note to be higher and raspier?

Which systems sound close to this one? :unsure:

Yeah a thread like that would be brilliant.

I'm just after the really high raspy noise just like that DC5, I'm not into the deep burbling farty exhausts. I like the Impreza's note but not the imposter's! Never sounds right and does your head in on the motorway droaning away..

DAMN that thang sounds bbbaaadddd B)
not sure to be exact, supposedly Fujitsubo is pretty lound but im not sure exactly how it sounds...when i was deciding exhausts it was between the Blitz, Fujitsubo, and HKS...but neither Blitz or fujjitsubo offered a Certification slip (for the exhaust) to pass inspection (japan rules) so i passed and go the HKS.
http://revver.com/video/217449/s2k-exhaust...subo-legalis-r/
here is a clip of an s2000 ...much different but there are other links with the S2000 that compare exhaust so u might be able to see some tonal differences
hope its helpfull...

I have the Fujitsubo Legalis R and its not too loud. Quiet at low revs and a nice rasp when the revs pick up. It also DOES meet the Japanese regulations as it is JASMA certified. Not as loud as alot of other ae111 exhausts ive come across.

Francis - the system I make without mid silencers can produce that sound you are looking for. I'll get a vid of it once I'm finished with my prelude one. It's just a 2.5 inch system with no silencer except back box.

That's exactly what I'd like. :D

Let me know how the Prelude system goes, if I order one of these systems from you we can do a before & after on the dyno. ;)

rasp is not the best sound to have... but each to there own...

having stuff all mufflers on a 4age will give you rasp, using S/S pipe and end muffler will also give it a tone change

yeah some are jasma certified, BUT some companies will not give you a physical Certificate for the "shakken" (japanese inspection) it was blitz that didnt have the certificate, maybe Fujitsubo was OK....did you get a physical certificate saying Jasma certified etc.?!

Yep there is a JASMA plate/stamp on the backbox, cant remember which tho.

Closest I'd say probably the Kakimoto Fullmega N1 (Not the Kakimoto-R) or the Apexi N1 :D

Kakimoto N1 - http://youtube.com/watch?v=ynQVshKzvNw

Apexi N1 - http://youtube.com/watch?v=nzKrk5IeVCc (Laugh at the sync between picture and sound :P)

I'm tossing up between these two and 5Zigen A-Spec :P Like saying do i want to go deaf or be kind to myself and those around me... Decisions decisions...

You love it too? =D Should hear the Fullmega Dual N1 on a GT-R, its beasty XD Back on track...

Thats the difficult part I think, not many in Britain deal with Kakimoto Racing, but grap your local importer to help you there. Kakimoto Racing website Link

You could try RHDJapan, Greenline or Nengun as they seem to deal with Kakimoto Racing.

That DC5 sounds awsome... i wish i can post my video somehow, since it's close to that but not the same...
still on a video cassette... need to record it digitally...

But my buddy club is too loud... it's not JASMA approved and is over 95db with silencer... and over 100db without so always have silencer on... otherwise get pull over by cops every second and everyone looking at ya...

I'm using Buddy club II... i got some ear plugs handy when i drive long distances.... :P

Sounds like fun! :lol:

Where did you get your BC II? Sounds like the system for me. B)

If i remember correctly the buddy club spec 2 is just a straight through exhaust, ie no silencers or back box. When I get the system I'll make one for you Francis. ;)

I got the BC II of a friend of mine who used to import their products into NZ... But he's closed the shop and went back overseas...

It's not that expensive either for a stainless steel exhaust... compared to other brands in Japan...

The BC II has a baffle/hot dog/silencer in the centre main pipe and a 10cm detachable silcener at the very back, done a dyno with and without that piece.. makes very little difference in power... only 1-2kW difference at the very high end of the power curve...

Here's what the exhaust looks like...

Posted Image

There are 2 springs included to hold the pipes together... you can leave them off since my one broke so many times that i just weld the 2 pieces of pipe together...

I also added an extra silencer where the cat used to be since i need it to pass the exhuast testing done by Low volumn cert guys... so just got it at 95db... ya pass that... no more excuses to the pigs.....

I have a buddy club spec 4 fitted. Extremely quiet at low revs, you don't even know you have an aftermarket piece fitted until 4000 rpms :D :D then the beast comes alive.

Newer designs like BC 4 is designed to be bit more quieter, since older ones are too loud and in the past the restrictions weren't that bad but now most Japanese aftermarket manufacturers have to comply with JASMA or some kinda of law for overseas markets too.... so now days not many companies make extreme exhausts anymore.... very seldom now...

Another one to consider is JIC one, Spartan DE Type 1 I think the one is for AE111...

Hmm interesting thread...

I have no sound at work at the moment but eager to here how these cars sound.

Are the usual HKS and Fujits.. still mental money for these cars? Do you noticemuch change in throttle response or torque when removing silencers?

Whats the standard system like?

Most trueno/levin owners go the for *loud* option?

Anyone ever gone to a custom shop to get one made up (I know they can be boomy) but was pleasantly surprised by one made up for my legnum.. well quiet on tickover very muted deep note... only roars at top end


Cheers
