rusty_wingnut Posted October 4, 2011 Share Posted October 4, 2011 I have recently converted my 300tdi 90 to a 3.9 V8 with Cats. I have to retain the Cats for the MOT due to the age of both the 90 and the engine (both 1996 ). Does anyone know of a supplier for a mild steel mid and rear section? I have retained the Disco's downpipes and cats upto the Y piece. Basically I am looking for everything fromt he Y piece backwards. I've tried Paddocks and the hoplessly expensive Rimmer Bros, will a 3.5 system fit my chassis and the Y piece without to many mods? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 4, 2011 Share Posted October 4, 2011 I believe the 3.5 is a much smaller bore, and is likely to strangle the engine somewhat, and not bolt up to the Y in any case. If it was me, I would take it to a local exhaust fabricator (often advertising stainless) and see what they think cost-wise -could be surprisingly cheap compared to bodging around another system to fit.

FridgeFreezer Posted October 4, 2011 Share Posted October 4, 2011 I'm with Bowie - get a bit of stainless bent up to spec & call it done. Or you can buy bends & straights from various exhaust suppliers / eBay and weld something up yourself. Quote Link to comment Share on other sites More sharing options...
tacr2man Posted October 4, 2011 Share Posted October 4, 2011 I used the non cat downpipes in my 110 3.9V8 it only required a small mod to Y pipe on outlet leg of Y (ex discovery) to line up with standard 110 V8 exhaust . it would seem logical that the cat type Y pipe would only need a similar mod to line up with standard V8 90 exhaust ,the parts of which dont seem that expensive from paddocks .The exh diameter on a 110 V8 does not look restrictive as its same as outlet on 3.9 Y pipe .

rusty_wingnut Posted October 4, 2011 Author Share Posted October 4, 2011 I would love to get something made up or make my own, but sadly at this point I don't have time and will be pushed to get the wiring finished for when I need it, so need something fairly easy and untime consuming Tacr2man was the standard 110 exhaust a 3.5 system? Anyone have any data on bore sizes for a 90 3.5 system? I know the Disco Y piece has around a 3" outlet Quote Link to comment Share on other sites More sharing options...
mickeyw Posted October 4, 2011 Share Posted October 4, 2011 Ah ha Dave, I've recently been messing with this kinda thing. Now depending on the engine position this is a fairly easy one (mine is original factory fitted 90 V8, but now 3.9 and auto). I have RRC 3.9 front pipes mated to 90 Td5 rear section. They fit together very nicely, although the front pipe on one side hangs a bit below the chassis. If you're coming to British Dirt/Mudmonsters at the weekend you can have a look.

rusty_wingnut Posted October 4, 2011 Author Share Posted October 4, 2011 Hi Mickey, Yeah I'd love to have a look but one big problem, I am still sat on the otherside of the North Sea Any chance of a few pictures though? I'll admit I should have done a search before starting this thread, I dug this out: http://forums.lr4x4.com/index.php?showtopic=12519 And i think I may try Nige's suggestion.
