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)

      R34 Skyline climate control unit transistor

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
