Brace sold!

I installed my exhaust myself as well, and i'm pretty sure thats the case for R33 regu 06&R did you do any measurements to make sure that the centre muffler is smaller than the restrictor in the rear cannon? or was that a visual estimate? the regu06 has a relatively small cannon already, so it can be a bit deceptive- the hole is actually smaller than you think- do this test- try and see if you can shove like a degreaser spray can through the smaller section of the cannon when the car's cold, if not then you'll realise how small the restrictor actually is. its less than or equal to 2.5 inch. and no way you'd even be able to put your hand through that the internal tube of the centre muffler is 80mm, and I'd be really worried if its the same size or smaller than the restrictor. its definitely not the case for R33, don't know about r34 but I doubt its different i think the "bang and pop" is more tune related mine does it but that's because my car needs to be retuned after i changed the turbo, does it with any exhaust, just more apparent with this one because other noise frequency is already covered by the restrictor my mate's R34 GTR doesn't do it as much because its been tuned

You must've put your hand in from the 90mm side, which is the short side of the mid muffler piping section from the picture i doubt you'd be able to reach the centre mufflere if you put your hand in from the long side the pipe inside the mid muffler is 80mm, same diameter as the piping on the long side between the cat and mid muffler the restrictor inside the cannon is definitely smaller than 80mm, but i dont know the exact size since i can't measure it

so you're saying that the perforated tube in the centre muffler shrinks from 3 inch to <2.5 inch? that can't be right, but i'm sure there's no reduction in there, judging from Kakimoto's website I think what you're talking about is that the 90mm piping reduces a little before it enters the rear cannon then yes, you're right, since the centre muffler entry/exit is 80mm- but this isn't even worth worrying about We're talking about the restrictor inside the cannon, so i think you're on a different page it's basically a silencer, but welded inside the cannon, as you can see in boostn0199's picture, and this is what is causing the restriction and not allowing the engine to boost over 16psi on my setting it's this thing try shoving a 2.5 inch pipe in your rear cannon when its cold, i bet you it won't get through as much as i'd like an exhaust without the restrictor, I have no choice but to keep the noise level down, since anything straight through (muffler or not) is too loud for my setting i hope this makes sense

I've got one insalled now, can confirm that its definitely got a restrictor in there Its probably one of the quietest exhaust i've ever had, and the sound it produces is really nice when you give it a rev problem is now the engine won't boost past 16psi, previously set to 18psi and goes there without a problem with any other exhaust i've used. my guess is the restrictor doing its job. at least now the missus is happy

yup bought stuff from this guy before, its genuine

here are photos of the AFM and the B pillar brace

Yup, will do tonight!

nope they're different r32 is generally thinner, different thread

seat and flywheel still available!

i think its worth the switch, r33s can make good power reliably, and better interior than s14 silvias are lighter so you can modify it to make it accelerate as fast as a more powerful r33, but on high speed the r33 will keep pulling due to the extra capacity it is bigger and heavier, but if setup correctly, it will handle just as fine, since it has front double wishbone to counter the extra weight the RB sounds better than sr20, and revs smoother

exhaust sold!

How much louder did it get after the restrictor was removed?

it's welded in see if an exhaust shop can somehow remove it for you... it looks like a bit of a mission to me

try this when this happens, switch it to hi or low (depending on which one you're on) and switch it back to your original profile again (hi-low-hi/ low-hi-low), try boost it, it should fix itself if you turn the car off and turn it on again, problem will come back, and the boost will spike again if it's exactly like above, then it means you'll need a new boost controller my profec B did this, so i changed it to AVCR

This looks exactly like the internal of the N1+REV cannon photo i've posted though?? the restrictor is right there.. without the restrictor, you should be able to see the perforated section inside, with lots of tiny holes on the pipe another way to test is, use the alloy rod with the hook end that comes in the skyline toolkit, if you shove the hook end in, you can hook the end of the restrictor if there's no restrictor, then there's nothing to hook On the other hand, V35 with regu 06 and metal cat sounds porn this is my mate's old car. was quiet when it only had the regu 06, but became significantly loud after he changed the Y pipe and the hi flow metal cat for some reason 350z doesn't sound quite as nice as the v35

Thanks mate.. it is truely a great exhaust, great throaty sound and flows really well unfortunately for me its this or missus...

Flywheel- $50.00 came off R33 gts-t, just needs machining. will post R33 series 2 GTST rear seat - $40.00 in good condition, pick up only HKS silent hi power catback exhaust for sale, for R33 GTST- $480.00 Full stainless, piping diameter is 3.5 inch~3.75 inch, good for anything from factory standard engine to high hp applications, good condition, and sounds really tough, unfortunately the missus doesn't like the sound pick up only, Will include genuine HKS removeable silencer Located in Chatswood, Sydney PM me if interested, no low ball offers please

good to hear that the regu 06 doesn't have that silencer thing welded in like the N1+rev, in that case it's a much better alternative over the N1 and some others like fujitsubo super ti last time i checked i think Blitz exhaust also shares simillar design, except the silencer opening is a lot bigger than the Kaki N1 +REV FYI The old kakimoto hyper 2000 N1 or HKS silent hi power and old Apexi n1 don't have it, but they're really loud

hrm that one in the photo's definitely for turbo r33, its Kakimoto N1 +REV, part number's N31307 same part number for GTST & GTR, 3.5 inch piping it was ridiculously quiet for 3.5 inch cannon exhaust so i thought i'll check it out, and that's what i found so i assumed that the regu 06&R probably shares the same design seeing that people say its quiet, thought i haven't heard one on an R32/33/34 in real life then i thought about my friend's r34 GTR with the quiet fujitsubo, had a look inside and found the same thing the r34 pulled 260rwkw with that exhaust, PFC and boost controller, and 30,000km but the engine blew after a track day, rods came out from the side of the block we couldn't figure out why, until i read this http://www.skylinesaustralia.com/forums/Da...er-t314520.html so i guessed that this might be a contributing factor
