Chaps,

I love the noise my '5 makes but I'm planning an evening with a madame & the only downside with the '5 is although it's superbly loud (Especially through the tunnels!!)... I want to be able to hear what she's saying rather than nod along as If I have a clue what she's on about!

I'm hoping there is a quick & easy route available for silencing which can essentially allow me to flick on/off the silencing or have the same ease as putting the roof up & down.

Does such a thing exist? What are the options? confused

You could:

Not drive as hard
Apologise in advance for the drone
Take another car
Have a conversation at the planned venue you're taking her instead wink

1. You know how difficult that is!
2. I did this prefusely on the last occasion & apologised many times over for her actually bouncing out of her seat from hitting a pot hole! hehe
3. Can't happen unfortunately.
4. Yeah, there will be that too. More along the lines of it sometimes drowning out the music.

Can't you just nod and agree?

That's what I do all the time, driving or not.

Just to be certain here, are you talking about silencing the car, or the woman?

I can't help in either case (though God only knows I've tried on one of them), just wanted to clear this up for certain.

Sorry, seriously though, adjustable exhaust baffle?

Like something you use on a track day if you're exhaust is too noisy. Stick it down the 'ole and it bungs up the noise.

If you think this'll work, I'm sure there's a thread on it in the track day section somewhere. Cost about £30 - £40 from memory.

You can get baffles that stick onto the end of the exhaust; you sometimes see them on track-cars where the noise limit is too low for their exahusts. I don't have any leads/urls for these I'm afraid.

Can you not just keep the revs down/change-up earlier?

Has anyone here had to silence their '5 for track days?

I always assumed it would be one of the few decent cars that could actually get through the more stringent track day tests.

ETA While I'm going a bit off topic, how much difference do the various hoods make? Mine was very noisy on the motorway - not a nice noise either - and I always assumed some of this was down to the cheap replacement hood. Do they vary much?

I have an (MX5 Parts) IL Motorsport backbox (and a CAT) and have always been well within the 100Db limit, which is IIRC about as low as track noise limits go. Think I measured 89Db last time I went, and with Db being measured on a logarithmic scale, this is well within the limit, I'd be surprised if you had an issue unless you are de-cat/straight-through and have a trumpet for an exhaust...

You'll not have a problem with an MX5 on a track day with pretty much any exhaust (bar a single length of scaffold pole). 100Db is actually very, very loud!

Disagree, the popular twin exhaust on my s/c was from p5 was way too loud for trackdays, with no cat (eunos so no cat was on it or needed) my previous turbo car had the same set up & again daftly loud, that was de cat on purpose tho, with the cat it was in fairness ok, with current one I whipped it off & put on the mazdaspeed one the car came with & its fine.

Not sure if I shoudl sell the p5 one on? whats the value ?

If only! Most evening sessions are 90-something (usually 98 or 99 I think) and they go down to 88dB at Croft and Goodwood I think.

Half the reason I sold the TVR was I was getting into the track day scene and having to pick very carefully which I attended.

Fairynuff - I've not done an evening session anywhere.

I've been on track/airfield days where the limit was something like 97db.
My car is pretty loud (Larini Sports cat & mid-pipe and Racing Beat Dual back box) but only reaches about 93db.
