Fantastic, thanks so much.
So it appears that the US does have a different rear muffler to the rest of the world.
So, it would appear the market configuration is as follows:
EU:
Rear muffler: 7 933 805 04
Centre section: (1) in below
V-band downpipe
GPF
"quiet"
AU:
Rear muffler: 7 933 805 04...
They do not. GPF equipped cars have a pressure line that runs up close the the rear turbine housing, and attached to a sensor.
A quick look in the engine bay confirms the Au cars don't have this.
Similarly, the centre-section of the exhaust looks the same as the US model (nonGPF) rather than...
Just took my A90 to get fuel in 15 degree cold weather.
Honestly- the level of crackles and tone sounds no different to this video - and wildly different from Mark (WTFs) Au car. That one does seem more muted... but I have done nearly 1,600km and have noticed the car gets noisier as it runs in...
Here's the AU rear muffler part number
Can someone in the US please snap a picture of theirs? It's very easy to access, just near the LHS rear inlet/outlet. No need to raise the vehicle from the floor.
I think any differences between those video could be in recording equipment. I shot mine on my 5 year old phone haha.
I have noticed the crackles are much louder when it's cold - but I am not too concerned about crackles (they're a bit childish anyway) but the main exhaust volume difference is...
Hmmm, good pick up. I never noticed the rear muffler being different.
I really only looked at the centre section (resonator and cat) as well as the dump pipe (slip join (US), not V band (EU)) plus no GPF
Perhaps we have the US dump and mid section, with the EU rear?
That said, in this video...
Made a quick video.
Things to note:
- The Au model does not have the GPF
- The exhaust hardware is the same as the US models - not the EU models (see pic)
- Exhaust flap is always open - except cold start
- Cold ambient temperature gives the really loud cracks and bangs - otherwise it's like...
Nah, our Supras have the same tune as elsewhere. One of the Melbourne dealers dyno'ed one within weeks and results were ~230rwkW, which is very consistent with the US results (Given US dynos predominately read higher than ours)
No, us Aussies have the burble and crackle. We have the US exhaust system, not the GPF one that EU got.
Whether it's as loud in terms of volume as the US cars, I have NFI. Maybe the crackles aren't quite as loud, but when it's cold ambient temperature- they sound exactly like US ones.
Also -...
I might just remove the centre resonator to start with for the volume increase, and go full 4" when I am ready for a tune (and flex fuel)
Are there any issues running E85?
