A lot of YouTube videos have TVRs popping & banging. I'm not a fan and neither will the neighbours be if I left in the wee hours! If I didn't want my (as yet unbought :-) ) Tuscan to do that, can it be tuned out, or dialled down a lot if not completely? Is a certain amount of what I'm hearing due to driving technique done for effect?

I can't vouch for these new fangled curvy cars with the speed six engine, but certainly for the Wedges a lot is down to driving style. If you work up and down the speed and gearbox in a considerate and gentle fashion then it's very civilised. If you rev the balls off it, and then take your foot off the gas at high revs, in say third, then loads of theatrical pops and bangs.

Its driving style - you can start up and leave home reasonably quietly in a Tuscan.

Obviously the nominal dB of the exhaust at idle is insurmountable but it wont pop and bang if you don't make it.

What is laboriously programmed and achieved with extra components in modern cars is home-made at TVR: There are pops and bangs in overrun mode. All the more so with a loud exhaust system.

With a discreet driving style, you have nothing to fear.

Und fortunately, the engine has no programming like a Maserati, Lamborghini or Jaguar F Type, which always roar annoyingly when starting up. So you don't have to worry and can leave the garage very quietly if necessary.

Pops and bangs are generally mapped into the cars but it’s fairly easy to avoid the Rev range they normally appear. On RV8 cars that tends to be around 1700 down to around 1400 revs which can be provoked by leaving a bit of trailing revs on as you slow down.

Any Tvr starting and simply driving in the early hours of the morning is likely to wake people up.

If the car has sports exhausts fitted or cats removed this will make it louder.
A TVR with standard exhausts is not particularly loud but given they have large displacement engines a deep throb is all part of the experience. Removing pops and bangs won’t effect that very much.

Can be tuned out.

Agree with other posters not necessary to to solve your issue, as easy to drive around it. Mine don’t pop and bang unless the exhaust is very hot anyway.

Also agree that general exhaust volume will be annoyance to neighbours. Bigger silencers for overall volume will be more effective than remaps for pops.

Ironically I fired up and drove my TVR for the first time in months the other day and when I returned home two separate neighbours including a lady over the road suggested they’d missed hearing it. rofl

Low revs, creep out of the neighbourhood. Mines quiet anyway but oly popps coming down from 4K to 3K revs so easy to avoid.

I used to live in a small village in Germany.
During the 22 years I was there, my daily drives included a Tasmin, 2 x Chimaera's and 2 x Tuscan's.

Apart from early office starts, I would often be heading to the airport at very early hours.
I never had any complaints as I would always keep the revs as low possible and just rumble out of the village.

In the village pub, one evening, one of the old guys commented that when he would hear my car, he knew it was time to go the bakery for his breakfast rolls. smile

FWIW, I'm not a fan of pops and bangs. Leave it for the Audi s3 brigade.
