duncmc Posted July 13, 2016 Share Posted July 13, 2016 Ok, here is my dilema.... I am in need of a new Y section for the exhaust on my 3.9 auto. The car has catalysts, and they are rattling badly because they are loose. I could just remove the inards, but then come next MOT time it probably would fail on emissions. A new part is ESR3059. This new ESR 3059 is only available from LR at £3260!!!! according to the Rimmer Bros site. There is ESR3063P which is for the manual 3.9 and is availble in stainless. Or a mild steel ESR 3060P for the 4.2 V8. Do I punt for the ESR3063P which might not fit in stainless, or go for the possibly wider bore ESR3060P which should fit but is 20% more and only mild steel? Rimmer Bros advice is risk the ESR3063P, but if I modify it they won't accept it back..... What do you guys think I should do? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 13, 2016 Share Posted July 13, 2016 What age is the RRC again? I'd check the regs, as with my Audi for example, it was fitted with a cat but it is old enough to pass without, and has done for many years. Quote Link to comment Share on other sites More sharing options...
Tal Posted July 13, 2016 Share Posted July 13, 2016 I learnt to weld because a similar price tag to fix a transit a few years ago. mild steel tubing of the right size can't be all that expensive and a cheap mig welder would cost only £150 or so....presuming you don't weld already that is. You might even be able to weld that up from flat sheet steel if you're feeling a bit brave edit just looked one up ......scratch the mostly daft comment about fabricating one but you could maybe fix it for now depending on whats wrong with it and is this it? https://britishparts.co.uk/products/7902-catalytic-converter-ESR3059 Quote Link to comment Share on other sites More sharing options...
duncmc Posted July 13, 2016 Author Share Posted July 13, 2016 What age is the RRC again? I'd check the regs, as with my Audi for example, it was fitted with a cat but it is old enough to pass without, and has done for many years. It was built in November 1993, and first registered January 1994. So as I understand it, from August 1992 cars had cats fitted from new due to tighter emission regs. So, without fitting LPG or something like that it would fail on emissions after August 1992. From what I can gather there are some loopholes, such as if the engine was made before Aug 1992, but my engine is a 1994 engine anyway.

But I would want to be able to TIG to do a neat job on an exhaust. Oh, and yes, that looks like the part. I am guessing that the internal ribs that hold the cat part in place have rusted through. I think my first plan is to take the Y piece off, and cut the cats open to see what is going on. Then go from there. Quote Link to comment Share on other sites More sharing options...
Anderzander Posted July 13, 2016 Share Posted July 13, 2016 For that money couldn't you get a custom exhaust place to make something up ? Or is it being a standard part important to the build ? Quote Link to comment Share on other sites More sharing options...
duncmc Posted July 13, 2016 Author Share Posted July 13, 2016 For that money couldn't you get a custom exhaust place to make something up ? Or is it being a standard part important to the build ? Not sure how much a new Y piece with new Cats would cost custom. I certainly will not be buying the genuine correct part! Quote Link to comment Share on other sites More sharing options...
Anderzander Posted July 13, 2016 Share Posted July 13, 2016 This seems to say it would fit ? https://www.ebay.co.uk/itm/261626286491 Quote Link to comment Share on other sites More sharing options...
duncmc Posted July 13, 2016 Author Share Posted July 13, 2016 This seems to say it would fit ? https://www.ebay.co.uk/itm/261626286491 So it does. That is back to the ESR3063 that I was thinking of getting from RimmerBros in stainless. http://www.rimmerbros.co.uk/Item--i-ESR3063P Quote Link to comment Share on other sites More sharing options...
Anderzander Posted July 13, 2016 Share Posted July 13, 2016 The stainless one is virtually the same price ! Give it a go Quote Link to comment Share on other sites More sharing options...
duncmc Posted July 13, 2016 Author Share Posted July 13, 2016 I think I will do just that. Won't order it just now though. I'll wait a week or so so it is delvered ready for when I get back from holiday. Thanks for the help. 1 Quote Link to comment Share on other sites More sharing options...

Snagger Posted July 21, 2016 Share Posted July 21, 2016 Could you not just put a couple of self tappers in through the cats to keep them still in their houses? Two Tek-screws into each block with a little exhaust paste under the screw heads should work. Quote Link to comment Share on other sites More sharing options...

I had thought about this sort of thing. but how long would it last......and then I would be back to changing the cats anway. Plus, will look better when I sell it.

Anderzander Posted July 21, 2016 Share Posted July 21, 2016 You're going to sell it Quote Link to comment Share on other sites More sharing options...
duncmc Posted July 22, 2016 Author Share Posted July 22, 2016 You're going to sell it Probably, (eventually) and have my eyes on the next one. Plus, marrital issues and can only keep/ justify 2 or 3 cars...not 4 Range Rovers plus a normal car. Quote Link to comment Share on other sites More sharing options...
