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I heard the trust pe2 system was good but apparently it has been superseded by a later model.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

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
