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..

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

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)

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.

      What brakes on R34 GTT(Europe)

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
