Im after a quieter exhaust for my r33 gtst as im trying to get my car engineered and my exhaust i got now is way to noisy (probly close to 105db). does anyone know of any quiet but free flowing systems that would be good to buy??? was thinking bout a blitz cat back system or something like that, any help would be greatly appreciated

There's the HKS 'quiet' zorst but i'm not sure how quiet that is.

Also, i think it's APEXi that have mufflers with a valve that opens under certain pressure so it's ok for cruisin and then opens up for the extra power. CHeck thier site. it has a flash of it working

get xforce varex..

got them in my car.. can adjust with remote till the sound almost like stock

correct me if i'm wrong, but i thought any exhaust system with an adjustable silencer was illegal.

recommend hi-tech mufflers. their exhaust systems are MADE to pass legal db requirements. and i'm assuming you're getting the car emissions tested, if so, obviously make sure your cat is carb compliant

i already have emitions test results, they just wernt done with my exhaust system, they were done with my mates system

my exaust was 3inch bellmouth dump to highflow cat to Fujistubo muffler - very quiet

I cut off the muffler and put on a Kakimoto muffler, much much louder.

I can sell the Fujistubo muffler if you want it.....

I have the silent hi power,

compared to the stock muffler that came with my car (factory option nissan sports muffler, it has a silencer aswell)

the hks system wasn't any louder on idle, just a deeper note.

The hks system actually is a bit quieter on certain gears & rpms, but when you open the throttle it absolutely roars.

Tough sounding exhaust note that doesn't drone or sound like a wet fart i.e riced up civics & lancers

    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
