How to Make the Supra as Loud as it Looks?

[MA617M]

The Aussie supra is quiet as shit with the valve open. In sport mode, it's open all the time except for higher gears on the highway, iirc. We have a different muffler to the USDM market.

The 2023 models are even quieter than the first release 2019 models.

I've got the Tomei Type D on my 6MT and I fucking love how it sounds. Not as loud as my other Supras, but you can hear it, and it's fine on the highway.

Greetings, also from Australia. Took delivery or my Manual Supra last week and you are right. It is waaaaaaaaaay to quiet.

I've just ordered a Active Autowerke catted downpipe for it... They guarantee no CEL. But it wasnt cheap. I paid $3,000 for it.

I've also ordered an MST intake with turbo inlet to get me some spoolie sounds.

Can let you know what difference it makes once installed. Or if you are in Sydney you can take a look at the car.

The Australian version has a different muffler than the US so it is much quieter. Luckily there is no OPF like the EU version which robs even more sounds

If I live in the EU (great roads but shit emmissions & sounds standards for enthusists) won’t bother to own a Supra, with that Corolla Hybrid soundtrack and heavily detuned B58

The easiest and cheapest way to get the sound back on the Australian Supra is to get rid of the muffler

I'm not in Sydney but would appreciate your feedback on it! Looks like I'll have to do something like this as its just not acceptable the way it is.

What specifically is different about the exhaust?

The muffler is different which reduces the db level much more so than the US version

The $$$ way to get more sound is to switch to an aftermarket cat-back exhaust system like the Tomei Type D.

The cheap way to do it is a muffler delete, using straight pipes to replace the muffler (check video below)

Interesting. Is it much louder with the valve open?

Speaking to my particular car, which is 100% stock '23 6MT except for the cat-back and has the aFe resonator delete, it's decently louder with the valve open. At interstate speeds (70+ freedom units, in the hundreds of science units) there is some drone but hitting the sport mode button to close the valve makes it quiet. Perfect.

I found this video of the AFE exhaust with decibel meter readings included. Louder with the valves open, but maybe not a ton more than stock.

The aFe Takeda has a middle resonator included, which given that video made no mention of I'm assuming they have it installed. You can buy a $80 delete pipe from aFe like I did, and then it's basically a straight-pipe with the valve open (yes I'm aware the Y with the muffler for the quiet side of the exhaust is doing some attenuation.)

Everything is V-banded so it's stupid easy to swap between the resonator and straight pipe as well. It's a good design.

Someone should post stock 21+ exhaust clip from the aussie land. Interested to know the difference than u.s/canada

Ahhh. Nice. Good to know.

This does sound like exactly what I am after. Freedom units.. hehehe.

I'm interstate for a while but when I get back I'll see what I can do.

I know a lot of people hate burbles and pops but the MT as delivered in Australia is disappointingly quiet. I've turned off ASD because ASD is stupid and even in Sports mode it is disappointingly quiet. I mean this car looks the part but my just sounds way too timid.

What is the cheapest and easiest way to make this car sound the way it looks?

Catless DP will make it loud af.

I have Catless DP and Magnaflow exhaust. If I use the straight pipe setup, it shakes the earth on cold start. And it's not quiet other than idle maybe.

Indeed.

For b, you'll want an exhaust that retains the valve and also has a meaningful difference between the quiet side and loud side. A lot of Supra exhausts (including the OEM one, bizzarely) really don't have that much difference with the valve.

I'm a big fan of my aFe Takeda with their resonator delete so far. It gets nice and quiet with the valve closed.

I have mbrp, and there’s a big difference between valve closed and valve opened.

What specifically is different about the exhaust?

The rear muffler has a different part number, which matches the EU Supras. I haven't cut it open but suspect it has more baffles.

AU is a bit of a mix, it has the US-spec engine and mid-pipe, with no exhaust filter, but the rear muffler is EU spec.

Tomei Type D with the OE cat sounds fantastic on the manual, not to mention the 12kg weight saving

Cold start is pretty loud, but that's a minor concern.

Tomei is cheap and loud. Combine it with a catted or catless downpipe and you get even more loudz

Is it street legal in the nanny state.. and do you know of any local purchase/install options?
