Hi guys, currently I have an exhaust on my r33 gts-t that came from japan and it's really loud (102db).

I was looking at getting a quieter exhaust put on to reduce drone on highways and such because I use this car as my daily.

I heard the trust pe2 system was good but apparently it has been superseded by a later model.

Some info on this new model that replaced the trust pe2 or any info on other good quiet exhausts would be appreciated.

I Heard hks silent hi power is good too but I don't know if it is as quiet as the trust pe2 or the model that replaced it.

Thanks for the help.

My exhaust is legal Db and next to some cars its hard to hear it idling... Its an Apexi with ironically "Super Megaphone" on the tip...

Any exhaust place should be able to quieten it down for you by adding a decent muffler?

You could get the Nismo exhaust for the R33. 3", two mufflers, quiet as f**k, no idea how it flows though.

Ive got a HKS Hi Power Silent exhaust. Its pretty good when driving on light load, comes up nicely on boost and high up in the revs. Cost a fair penny to buy brand new though.

Pretty sure you can get 3.5" or 3" mufflers from anywhere and get any exhaust to chop up your current exhaust and weld in the muffler. You could then get a resonator or hot dog to lower the drone of your exhaust.

What exhaust exactly do you have? Is it stainless or mild steel? There really is no reason why it can't be shut up a little.

I have straight pipe 3 inch with a hotdog in the middle and a varex. 99db open 77 shut... and my engineer signed off on it. Just dont hit any boost when shut or bye bye to every seal in the turbo and probably engine!

Im really happy with it, not drony at all and so quiet when shut on road all i can hear is my injectors clapping away..

and open for full noise applications :-)

kakimoto r is probably one of the best high flowing quiet after market exhausts you can get for a r33.

every japanese after market exhaust will most likely be over the legal limit but getting close to it is what the kakimoto r does. i've had 2 series 2 r33's and i had these on both and on idle they almost sound stock and on boost there is more of a deep growl but its just right.

this is on a hcr32

Thanks for the advice guys. The guy said that because of the way my exhaust has been made, they can't just put in a muffler. So I actually have to go for one of the exhausts mentioned in this topic. Has anyone used the trust power extreme GS? Its supposed to be the one that superseded the trust power extreme 2 and I heard the power extreme 2 was fairly quiet. The hks silent seems to be mixed with some people saying its quiet and some saying they get high dB readings. I'll have a look at some of the exhausts mentioned in this topic.

I have an HKS Hi Power Silent too.

Instead of chopping it up i just made a replaceable center section with a muffler. Goes between the decat and the tailpipe section.

So when im on the street i use the quiet section, and when i want some roar i change it out for the HKS piece.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

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

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
