Decatted - will I get under 105db??
Discussion
I decatted my Carbon Canned mk1 Tuscan (after an MOT with nothing picked up!)
To help I used the guide on here (sorry lost the link) - really helped! Allow 2 hours and a lift will make it much, much easier.
Good to have a propper chassis check, happy mine is in good order - interesting how much heat the cats produce - definatly need to treat/protect the cat area.
I was expecting it to be too loud but was actually suprised that it not that much louder. Its different, lots more pops, it sort of roars when off throttle (not sure if I like it or not). I've not had a hoon yet, due to the unique british summer.
BUT....
I am booked on the TVRCC track day at the end of Sept.
Have I got any chance of passing the noise regs if I put on teh standard pipes?
I measured with a cheapy maplin noise tester yesterday - supposed to be accurate to +/- 3%, so .....
CCC at 2m and 45 degrees at 4000rpm = 108db (so 3%......max should be 111db and min would be 105db)
Decat " " " = 108db - yes really the same (didn't sound any different either)
What-do-ya-reckon?
Would rather not put the cats back on (not a pleasent job!) but don't want to be booted off the track!
I might be close to Anglesey track this weekend so might ask for a noise check with and without the CCC.
Does no one sell 'mega muffled' rear pipes - sure it would be easy to do?

Give Simon (Ex of CCC) a call 07899771944. He made me a set of quiet cans a couple of years ago for my Tuscan after I was over the 95db noise limit at Zolder. Made a fair difference. Have used them since on my Sag at a couple of track days. Brought both card in under 95db. Although neither were de-catted. But may make the difference if you are looking to come down from 108 to under 105.
We played about with other options, made up some db killers, but were a pain to fit.
A spare set of cans is the way to go. 20 minute job to change them over.
TVRowner, r u playing on the 28th ? Or is it just racing now ?

Testing and racing at Anglesey the three days before Gary, and then Oulton two weeks after. Last two race weekends of the seaon and don't want to put the racer at risk on a track day. Also need to earn some cash in beteween to pay for the racing...Garry
Was at Coombe for a track day two weeks ago (learning the track as racing there the same weekend).
It was nice to see the old track day faces. Racing only for the rest of this year and possibly next (with the exception of the big Z).

Your best option is to see if blackiepaul still has his pipes for sale. To help I used the guide on here (sorry lost the link) - really helped! Allow 2 hours and a lift will make it much, much easier.

Unfortunatly not.ACT do them but they seem to charge mega-bucks - be cheaper to take it to garage everytime and pay the £50 to swap them!
I cannot believe there is not a cheap and easy solution to this - does no one with de-catted tuscans ever track their car?

I have a decatted MK1, with CCC I run 113 db and putting the std end cans back opn gets me on Bedford and puts out around 98 db.
Now thats what I want to hear!!So the limit was 105db and you did not get kicked off? 98db would be fantastic - safely below the 105db
If I can find my original cans will attempt a proper noise test in Anglesey and report back.
Everytime I ask a track question I seem to get little resposnse - do not many take their TVRs on the track?? I bought this car to advance my driving.
I've asked about pedal adjustment before (no chance of heel and toeing with brake pedal so high) and got a similar level of response....

How do you mean brake pedal to high?. I find the Tuscan, as a "standard" car, the easiest to heel and tow i have driven, most other cars needing adjustment, or plates added to the pedals.

on the day I will be attempting to go on the track decatted and with standard blue flame pipes. I expect this to be on the limit but it is worth a try. If I fail I fit my silencers. If I pass and someone else is struggling they can borrow them as long as they leave a deposit of some sort. ....
The other way to look at it is that if you borrow them just for a noise test you will kow what your car would come down to if you bought some.

I have taken mine around a dozen trackday's so far, and find it a fun car to keep you on edge and progress your skills. The brake pedal is easily adjustable, just move the circlip and bolt between the two holes on the pedal and find what feels best for you, you can also adjust the length of the plunger arm to set the upright angle to some degree.
The std cans really do make it quiet enough for me to pass the tests, I only have the cats knocked out though and not new proper decat pipes..

My cans are sleeved and I can just creep in under 105db if I keep my lead foot still enough 
I know what you mean about "track day" questions though.
Seems like a lot of people on here worry about all kinds of stuff instead of enjoying the performance.

I don't suppose it was the quicket car on the day, but it was the car that everyone wanted to talk about! I should mention I never opened the bonnet once LOL, whereas many japanese cars had serious mechanical failures (turbo seals, head gaskets etc), the porker spun out and a VW V6 owner put his on its roof!
We are hopefully back again on the 4th of October... if the clutch doesn't go or the engine blow or maybe a "clonk" will be heard in the rear end, or the Racing Reds will leak, the windows not wind down or up, the doors pop-open at speed, or the radiator leak. The main fuse could blow, the throtle cable break, the battery fail or a stone chip appear on the service bonnet and a spec of dirt linger on the underside of the chassis where nobody can see it for more than 5 seconds..... ohhh gaaaaaawwwwdddddddd!!!

I had my Tuscan noise tested yesterday at Goodwood and with standard carbon cans on, it regrettably failed the test (105db) at 108db. I was also warned that on the drive by, I would likely fail outright (the stewards comments were that he could hear me approaching the track from the road outside so already had a sense I would fail!).
Aside from the expense of silencers (really don't want to do this as I only plan the occasional track day), do the standard cans really drop the noise down that much (10db?) as I believe I have them to hand somewhere. If swapping over is easy, this could be the solution.
