F1 Mclaren exhaust, weight saving

This is taken from a book my bro bought in the UK, cost him $200Aus and is mainly written by Gordon Murray and Ron Dennis.
".....The volume of gas blasting through a 6.1litre V12 engine at 7500rpm demands a very considerable exhaust system, whivh to meet international market regulations - as researched and monitored assiduosly at Genesis by the dilegent Harold Dermott - would require state of the art pollution trapping catalysers.
Silncer box volume needed to be a whopping 65 litres - the size of a loosely rolled double bed duvet. At Genesis Gordon almost despaired: "That was going to be seriously heavy, and how could we house it? Then the idea dawned. Because the engine and transmission were providing the chassis structure at the back of the car there was nothing at the tail we could use as an impact-absorbing crush structure, beyond whatever body panelling we would end up with there. If we shaped this enormous silencer box to run the width of the car, immediately inside the tail bodywork, that could double up as our crash pad".
One item, multiple functions - yet again, race-bred engineering at it's best. But what could a V12 exhaust system, feeding a 65-litre silencer, possibley weigh?
The Fax flashed back from Munich - exhaust system in standard BMW production steel, 100kg. This was blasphemy to the weight saving zealot.
Gordon flew to Munich. "paul introduced me to the guy who was responsible for designing the exhaust system, and winked at me, encouraging me to put on a show in the middle of the design office - to encourage others."
"taht made the guys not only realise we were serious, but also encouraged them to start thinking - really thinking - about the weight saving problem, and they began suggestiong good ideas, initiating stuff - and one saud why not use inconel for the exhaust manifolds...."
This stainless steel alloy is highly heat resu=istant, robust and light - used commonly in very high temperature turbo charger installations. Thinner guage sections could endure exhaust system duty, and it was inherently lightweight. Downside - it was very expensive, on weight grounds alone it had to be the answer. The manifolds were fabricated in 0.8mm wall thickness inconel piping, the "double-duvet" box fabricated in stainless steel- the Mclaren sports car exhaust system alone cost as much as a small family sedan.
This book was very expensive but incredibley detailed with blueprints etc etc, it is THE definitive F1 Mclaren book.
