DB Rating on a fujitsubo exhaust?

[Horus]

Im looking at getting a fujitsubo exhaust for my S15, but I was wondering does anyone know how loud they are, that is how many decibels they are rated at? I know they are quiet, but Im not gonna get one if its not quieter than my current exhaust, so does anyone have some info?

The Fujitsubo Legalis Super R apparently read 91db

Should tell you all that you need to know (youll need to get it translated obviously)

RMS also have decent prices on them brand new (they dont have the LegaliseR for the S15 unfortunantly, not that i see there...but im sure they can get it in if Fujisubo make them)

hey sam,

i read that the power getter (exhaust i have) on an s15 is 93dB at 4800rpm

[~Hypnotik~]

I've got a Fujitsubo Power Getter on my S13 SR20det. It's an awesome exhaust, doesn't drone when driving at a constant speed but ROARS when you put the foot down.

I got mine dB tested and it was 91-92dB at 5500rpm. Get the Power Getter, you won't regret it!

[SS8_Gohan]

aren't all those dB ratings too high?

[doridori32]

You cannot judge dB rating off sheets.

All custom pipe bends,piping size,cat size,muffler size,turbo size,engine size matter in this case.

Considering your car is still stock block/turbo/front pipe, you could use there readings for a "guestimate".

sweet as, thanks heaps guys, looks like Ill be getting one

[saff_cossie]

I think the db rating is 93 max for road legal as mine was borderline from memory.

Hey,

the dB rating for vehicles built after '84 is 90dB pre-'84 is 96dB as stated on VicRoads website...

I think it's post-86 must be 90db or under and pre-86 is allowed up to 93db. motorcycle is allowed up to 96db.

[SS8_Gohan]

so 'on paper' these exhausts wouldn't pass EPA?

[R32Big_boy]

Nope, has to be 90db or under. So they still wouldnt pass on papaer.

[foznice]

how far away is the exhaust measured from? and how high should the car reving?...they must be have agreed on something right? otherwise these guestimates would be pretty inaccurate....

Hey Horus, I'm running a Legalis Super Ti on mine, quiet as a mouse and good power. Let me know if you want a listen. Fujitsubo are well know for good power with low noise.

I've also drivern a 34 with the same mods with a Power Getter and boy was it loud, droned like a mutha and wasn't very nice IMO.

Hey,

On sound test they want you to rev up to 3/4 of your tacho (i.e. 10,000 rpm tacho = rev up to 7,500 rpm) i think, correct me if i'm wrong

Cheers

[foznice]

ahh ok... sounds good what about the distance??

[Count Grantleyish]

Hey,

I'm not too sure about distance but i might have some idea...

1 metre from exhaust (I THINK)

Correct me if i'm wrong

Cheers

Grant

[aybee]

i think 1 metre at a 45 degree angle

[foznice]

ok... so for an RB you would have to be revving at 5250, and all cars are measured 1 metre and on a 45degree angle.

I heard that it was one metre away somewhere else as well, so it probably is 1 metre.

I have the FULL Legalis Super R system on mine (extractors, full pipe etc) it was rated at 92db. But due to ADR's I've put an aussie highflow cat (Magnaflow) and a resonator (Blackbox or Blackwidow or something). The only reason I got the fujitsubo is coz it came with the car in beautiful stainless steel.

If you were buying local don't be a brand whore, just buy a locally built exhaust system and put a fujitsubo muffler on the end if you really have to. At the end of the day its a bit of pipe with a bit of cotton on the end in a can, and any monkey can weld that together... even an aussie one.
