Trev’s Disco 2 is guinea pig for a new com­plete sys­tem

Land Rover Monthly - - Dave Phillips - TREVOR CUTH­BERT

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.
