Winter project / exhaust update
Discussion
I had been looking for a exhaust solution for my 350i for some time and I had tried a straight thru system for some months. Bottom line it was just too loud (Motorway ringing in the ears!) and was getting some unwanted attention from our BIB! Some readily available systems are very good but also expensive and did not really give the sound I wanted from the RV8.
After some discussion with a bespoke exhaust company in Essex they came up with the box below. It is SS and costs £100 + VaT made and fitted which took them an hour to do! Just enough time for Full English at the cafe round the corner! Well pleased as it has a good loud and bass sound and small "footprint" so it does not catch but the most agressive speed bumps


Cheers

hmm...from 1st view i would say the box itself is not stainless, only the pipes are. but its your car, so you must know it.
That is what I thought ..Stainless input pipe .. with an aluminised mild steel box .. a slightly odd combination but perhaps they just knocked it up as a custom job. The price was bloody good.
No magnetic construction guys.....! This was a one off made by the guys in Basildon for me. I had asked for a good tone, free flowing box with a small foot print to miss those agressive road humps. Have to say that IMHO it sounds great, and touch wood does not seem to catch on the more agressive humps so happy!
One of the new neighbours was muttering about the volume of the 390 whilst it was idling t'other day; I pointed out that the exhaust was as TVR intended it. His response (I didn't catch all of it for the noise
) included the words 'construction and use regs' which I shot down with the term 'small volume manufacturer' 
Seriously though, I think that although the exhaust is largely stainless, the wadding almost certainly wasn't, so I was contemplating plasma-cutting the top of the silencer off and repacking with some stainless steel wire wool... until I realised it's £30 a KILO...
Still, a couple of kilos of that would be cheaper than having another silencer made.
