Hmm…the regular exhaust doesn’t sound that bad either if you get the engine above 3000 or so rpm….which basically never happens with the original gearbox.

Sounds like an old school big six you will need to spend some serious money and build a custom set of headers if you EVER want to make it sound like a v12

At low rpm it sounds just like the ww2 planes with RR and Packard merlin engines due to the firing order being the same and both being v12s

Is it healthy to shift automatic like that?

I’ve just picked up a second hand tt extractor system and I’m gonna fit a magna flow x pipe and see how it sounds . Wonder if adding mufflers to the end effects the v12 sound negatively as to fitting any silencers before the end of the pipes ?

No X-pipe on this setup. When I was running the stock manifolds, the X-pipe did change the tone a lot. It had more of the “V12 tone” forsure. This setup is headers merging into a single 3” pipe out the side. The headers made a massive difference in tone. The video does not do the car justice, I am really happy with the sound the car makes.

You can get 16-18 mpg out of them - if you glide through the landscape instead of stepping on it. They used to be fast for their time with a relative high top speed of 144mph….which is limited b6 the gearbox ratios.
