Sunray-I40 Posted June 23, 2014 Share Posted June 23, 2014 My whole exhaust system is rotting and will soon need replacing on my 1995 Defender 300tdi CSW 110. I am considering the expensive stainless steel route. I'd like to increase mpg and unlike some I don't want noise! What are the advantages of stainless apart from longevity, and what systems are recommended (and for what reason)? If there's already a thread on this, I haven't found it! thanks Quote Link to comment Share on other sites More sharing options...
western Posted June 23, 2014 Share Posted June 23, 2014 Double S system on my 200tdi engines 110, been on for nearly 18 years with no major problems, changed to SS simply because it last much longer & I hate working on exhaust pipes.

Maverik Posted June 23, 2014 Share Posted June 23, 2014 I got a really quite competitive quote from double SS the other week inc postage, considering I replaced my system on my 90 new 3 years ago, some huge sections fell off the other day! - I priced up £180 for a steel one and SS quoted me £380 for a 200tdi 90 one (full) or a bit cheaper minus one of the boxes. I got sent the price for a 110 too and that came in at £366 (full). I've botched mine by welding in some new/old sections - juts waiting for a month with less outgoings and I'll be investing in SS... For land Rovers I think the main advantage is the corrosion, you can get performance increases associated with SS from the only aspect of installing a custom manifold etc where you get even back pressure balance etc. So I'm not sure you'll find much info on any other benefits other than the obvious....

Tanuki Posted June 23, 2014 Share Posted June 23, 2014 Double S are pretty much OK, though on some of their systems I've seen they've not used mandrels to form the bends so there's some reduction of cross-sectional-area. The other outfit worth checking out are "Longlife" - they'll make a system to suit your requirements. Quote Link to comment Share on other sites More sharing options...
Taffia Posted June 23, 2014 Share Posted June 23, 2014 I have just had a 300tdi auto conversion on my '95 110 ex MOD FFR (was 2.5Na) and in the end went for a Griffin exhaust - haven't played fully yet but the quality is excellent and lifetime warranty plus they can tweak it to you needs. 3" pipe that doesn't wake the neighbours at 6am - I wanted better breathing, long term warranty and quality! Customer service was excellent and I am looking forward to giving it a full review once I can get some proper miles on it and have some dials fitted for temp, boost, revs and egt Taffia.

CwazyWabbit Posted June 24, 2014 Share Posted June 24, 2014 I could sell you a Double S utility system, two sections have had half an hours use and the rear section has never been used. History is I fitted it, didn't like the restrictive bends in the rear section, Double S remade the rear section (mandrel bent) but in the mean time I had gone out and bought a Griffin exhaust. I'd like £200 if you are interested, my original ad was http://forums.lr4x4.com/index.php?showtopic=84563 It's still in my shed somewhere as I never got around to putting it on ebay.

Hmm I'm also rather aware of cost, how much did this cost you? Quote Link to comment Share on other sites More sharing options...
