Agree with Adam. Unless you want to buy your own meter, I'd suggest a trip to a track day - they'll do a static test at .5 metre @ 2/3 and 3/4 max revs and let you know. (Castle Combe - Wiltshire?)
Don't think MOT testers have anything like that gear.
The other way (first) would be to post your cars spec on a TVR forum - cos unlike other marques, I think TVRs roughly rate at the same noise levels (unless you've been tweaking!)

I have a feeling, but i'm not totally sure, that the police have DB equipment for cars. I think my local constabulary were testing a couple of towns away after a few complaints about the noise level of the Max P mob!
One guy had an Escort Cossie that had been tweaked, tuned and modded so much it was producing 140Db!
They questioned him about various thing including the cats, he said they were in place, a plod from the stolen car squad (or whatever they are called) had a wee look under the front bumper, cat sensor was hanging down ann taped up, so they did an emmisions test! 
failed it miserably! They made him put it through another MOT, I think there in the process of trying to prosecute for driving a cat car without them, oh, and the noise!
So try your local plod shop, one in a big town such as Barnstaple, Bideford or Taunton (depending where you are) would probably be your best bet!

Plod have tryed testing noise levels with a dB meter at the road side before and come unstuck the actual regs are very complicated about road noise levels (hence why they are not in the MOT) and require the vehicle to be driven through a large circle at set revs with the meter on a tripod in the middle (but don't run it over) the biggesr prob is that the test area must be totally flat and away from any buildings or follage to stop the noise resonating off of the sorroundings for it to be enforcable so no where near as easy as speeding and hence not enforced. I would suggest that the best people would be, any local exhaust manufacturers ?? (don't know any in devon), Local environmental health dept at council (have them for noisy party complaints), local HSA or the Health and Safety dept of any large manufacturing sites or quarry as the noise levels form part of a risk assessment on machinery.

I believe Bookatrack will rent you their meter (for around £10-£20 ?). They post it out, you post it back 2-3 days later.
V worthwhile I would think, especially if you can take it to a pub meet or suchlike.
You can BUY a meter for £10-£20! Just go to any good Hi-Fi suppliers. There are endless ways of taking the measurement (revs, distance, smoothing/peak hold, A/B scale), but there are a couple that are pretty standard. Suggest you give the track day organisers a call to find out which type of test they are using and be prepared for the actual measurement to vary on the day - these measurements are not very reproduceable.

Not just large manufacturing sites any factory should have or able to lay their hands on one.

I have a Chimeara 450 which had a sports exhaust when I purchased back in Oct 01, had it tested at Brands in Feb @ 111db which is too loud for most if not all tracks, had the system reverted to standard & attended a meeting at Goodwood (105db day)who are very, very hot on noise, passed at 100db, however went back on March 30th which was a 98db day with additonal silencing & passed at 96db, the point I'm making is there were several other TVR's there that day including Griff & Chim 500's all of which passed without additional silencing, so if your exhaust has not been altered you may be ok & if it has get it checked before you pay out for a track day, as mentioned before most circuits will test it for you FOC, one other thing to perhaps remember is that noise meters have to be regularliy calibrated therefore you need to test your car with a reliable source to get an acurate reading, good luck

Maplins I have, but can't locate the meter. 400SE to get track legal
Cheers in advance.
