My super drager was buggered in the cannon, all rusted and crumpled some how.. Causing a restriction enough to hold back a 12psi actuator to 8.5psi. Cut it open cleaned it out so its hollow but its very droney now lol :down:

I've got a hks super drager on my 32 and it isn't loud at all. I may go down the path of removing the mid muffler to a resonator to get Abit more sound out of it.

Thought long and hard about doing this to mine as well.. but it is nice not being stung every time I get to take it for a drive.

LOL

Not only chicks,

I like to hear my turbo and whether the engine is pinging.

Also it is nice to listen to the radio.

A noisy exhaust doesn't cut it .. nor does a dump-valve ;)

The chicks love the quiet exhausts. Then they think they can talk the whole time ur driving

Just to recap on the topic

I installed the exhaust and it is quite loud :(

There's a heavy low rpm drone which is more behind the car than in the car.

I got a lot of angry looks from people at bus-stations (if you know what I mean)

It's a bit much for city driving, and I will try to get the drone down with one of these mini silencers.

I suspect the exhaust is so noisy since I have no CAT installed ...

Its noisy cause there practically no muffler, a rear cannon like that will do nothing if its straight thru.. its not much different to having just a straight thru pipe on the end...

I used to have the exact same on the back, now i got a proper muffler and still make the power and it actually sounds alot nicer..

Which muffler did you get?

I found this one ...

Maybe worth a try (I'd get it cheaper)

a cat and a middle resonator/small sized muffler will help out a lot.

i cant say if that one will help much, i would guess it wouldnt cause it looks smallish...

I have a 3 1/2inch system with hotdog resonator and a 3inch X force muffler ( large oval) , the muffler is semi straight thru and forces the exhaust into it to muffle the noise , but obviously its flowing great cause it made well over 300kw..

I think you would be happy with a similar setup, it has a nice muffled , tough note thats quiet enough to hear your radio without dronning. can hear it in my thread on the dyno...

on my GTT i had a Hypergear OP6 Highflow and a R33 Super Dragger :), R34 is slightly shorter, so it only needed a little modifications. Mine was very quiet, running a CAT obviously (you're stupid not to) and i THINK there was maybe another section in there that's different to yours.

when idling i'd get people asking me if my car was on :D - but had a nice note, didn't drone and flowed well enough for the situation.

Thanks,

I removed the CAT 3 years ago, it's common practice here since (older) JDMs can get away with it.

(Removing that CAT actually made a big difference, so why is that stupid?)

Also my car was tested for emissions recently and it was all to plan, no complaints.

However I am considering getting a high cell count CAT.

I am certain that would also solve the noise issue ..

must of had a silencer somwhere.. cannons will never be quiet.. not like that..

put a high cell cat and you'll take some edge of it, better off with a 100cell cat or no cat, and a good sized oval proper muffler, semi straight thru

Hi,

What small box do you mean?

Do you have any pictures?

Suprised, seeing the pic.. as the one im about to put up for sale has a small box.....

And it wasnt to loud or drowny at all.

actually sounded good!!

Yep, I agree a 100%, cannons will always be on the louder side.

(especially when they are 3.5'' in diameter)

As for the CAT if I could find one with a 3'' flange that would be great.

The standard CAT is just 60mm (3''=76.2mm)

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
