First run with my new decat Y piece
Discussion
Just thought I'd post this for anybody thinking about changing there exhaust. Well took my precats out last year and there was a slight increase in noise but nothing major. A friend has precats out and a sleeved exhaust and I found his a bit annoying, ok for a quick blast but annoying after a while. So I decided to try one of Clives decat Y pieces, pre cats out and standard silencer, well firstly big thanks to Clive the decat is very impressive to look at and easy to fit.
Once fitted I found a nice increase in idle noise plus slightly deeper tone and when giving it some it sounds glorious, now the main plus point for me was when doing motorway speeds I couldn't tell any difference to before I fitted it, so for me best of both worlds sounds great when you want but not to loud to be annoying if your travelling somewhere!
Can't comment on what differnce its made performance wise as I haven't driven it for months so cant tell the difference anyway!
Hope this helps other people make the decission of all cats out, standard silencer.

Nice write up Mike - I am in the middle of preparing my new manifolds (cleaning, de-pre-catting, POR20 paining etc) and can't wait to put it all together in the coming weekends.Once fitted I found a nice increase in idle noise plus slightly deeper tone and when giving it some it sounds glorious, now the main plus point for me was when doing motorway speeds I couldn't tell any difference to before I fitted it, so for me best of both worlds sounds great when you want but not to loud to be annoying if your travelling somewhere!

My back box has not been sleeved, but 'something' has been done to it......
So I will give it a go, and if it is too loud with Clives Y piece, then I will get the rear box back to full standard.
Cheers

I have also fitted one of Clives y-piece'. Couldn't belive it fitted easier than either of my standard y-piece' 
Superb quality and delivered when said. Nice to report on a quality TVR product/service. 
I also have precats out but silencer in place [though it is half size, a semi-sport I belive from factory,,, anyone else?] Keeps it muted cruising and nice bark on load pedal.
PS: have a ceramic coated standard y-piece for sale.

I've just done almost exactly the same to mine. pre cats out, ACT de catted y-piece and standard silencer.
First run out on Saturday and I can report similar findings to the OP - slightly noisier but nothing too much at normal speeds - but.... give it the beans and it sounds more raspy, more race car than road car.
Still can't get any pops and bangs out of mine on the overrun though!

I also have Clive's beautiful Y-piece, similar experience to the OP. Lovely sound at idle and only slight increase at M-way speeds...... worth the money just to look at though 
I would be interested in some manifolds at a later date.
I am also having issues with popping and banging, or lack of. Tried all sorts, guess she is just set up to well and not chucking any unburnt fuel down the pipes
