Trev’s Disco 2 is guinea pig for a new complete system
y great and talented mate, Dan Dew of Demand Engineering in Ipswich, delivered my beloved Discovery 2 back to me recently. The Land Rover is now sporting one of his fine stainless steel exhaust systems – although this one is a new departure from his normal work.
Around a year ago there were a group of us at Demand Engineering on one of Dan’s ‘work weekends’. This is where we are all assembled to carry out a long weekend of spannering, and the like, on some project or other that is in need of moving forward – with the promise of food and drink for all, as well as some special favour. This favour is a product or service from Demand Engineering at a good rate, in exchange for our efforts. Contrary to what some might say, these work weekends are not slave labour – “honest they’re not”, Dan would say.
At the time, I had recently experimented with Range Rover L322 ownership – only to find it was not for me. As a result I had just bought my Discovery 2, having found a good clean, well spec’d model. This is a Land Rover for keeps, in as much as one can keep one forever. Top of my list for the Discovery was a stainless steel exhaust, so I enquired about getting one for a good price in exchange for my efforts. “How about one for a really good price, Trev?” said Dan. The deal was that he would have my truck for at least one month, in order to carry out some development work.
In order to tool up, and jig up, to manufacture repeatable, off-the-shelf exhaust systems for any given model of Land Rover, a subject vehicle needs to be in the workshop for an extended period of time; hence the term ‘development work’. Dan had already done this for a number of Defender models, including using our friend Justin Thorburn’s beautiful 110 Puma Station Wagon to produce a twin pipe stainless steel exhaust system. Now thanks to my Discovery 2, there is a further stock offering
Mfrom Demand Engineering for owners like me. The exhaust that is now on my Discovery 2 is a complete system in high grade stainless steel running from the exhaust manifold, all the way to the lovely titanium tip. There are two silencer boxes within the system and, of course, a catalytic converter to keep it legal – and keep the MOT testers off my back. The two-silencer system is very quiet indeed. But fear not – the development work does not stop here. Dan has supplied me with a straight-through middle pipe and a straight-through rear tail pipe. This allows me to carry out some research on what the system is like with one silencer in the middle, one silencer in the rear and no silencers at all. Along with my current configuration, this gives me four types of exhaust system.
I am very much enjoying the civilised and beautifully free-flowing system in place now, but it is going to be fun to experiment with higher noise levels.
Interestingly, a client of mine – who is bringing his Discovery 2 in to me for some major work – has ordered one of the new exhaust systems, having seen and heard my own. He is chap much like myself; having some extensive work carried out because he plans to keep his trusty Discovery for a very long time.
