Cat /Manifold DIY fitting kit

MRBILLYUK · Sep 7, 2016

Having owned my 182 for 10 and half years and going through God knows how many fitting kits because they rust away within minutes I thought I'd have a go at making an alternative using all Stainless parts .

I don't know if anybodys interested , but there are the parts I used

M8 x 75mm stainless bolts
http://www.ebay.co.uk/itm/201443036339?_trksid=p2055119.m1438.l2649&var=500622995977&ssPageName=STRK:MEBIDX:IT
M8 stainless locking nuts
http://www.ebay.co.uk/itm/M2-5-M12-...hash=item35dbf833c0:m:mxSIktvYrUW7ObGElLKvYTA
M8 x 25mm stainless countersunk washers .
http://www.ebay.co.uk/itm/A2-SOLID-...W-CUP-WASHERS-CSK-SOCKET-METRIC-/360796868434
M8 serrated washers.
http://www.ebay.co.uk/itm/201466471743?_trksid=p2055119.m1438.l2649&var=500646180121&ssPageName=STRK:MEBIDX:IT
I used the original springs and had some stainless end caps for the springs made at work.
Time will tell if they last . Surely It can't be any worse than what Renault have to offer. Fingers crossed :tongueout:

It wasn't leaking from there , but the cup it sits in , in the manifold had rusted through again , so one side wasn't holding it on it was just merrily rattling away. I live 30 miles from the coast . I can honestly say , including today I've changed the kit 6 times , always using genuine Renault parts , only once did I use a kit from Northwest performance. Either I'm unlucky or you're lucky lol.

Can you get the wire ring gasket as a generic part as well?
I meant to measure mine last time I changed it, but totally forgot till I was driving the f**king thing down the road two days later!

I used a new one from a Genuine Renault kit I'd had for a while , although the one I took off wasn't in too bad condition .You can buy them on ebay. The seem to be listed under 2.5" donut gasket . You'd probably be able to get one from a local exhaust place.

I remember those ones from Northwest performance, rubbish fit, had a look at mine last week and the cups where still keeping the bolts in place.
I live in Norwich so its a 22 mile drive to the coast,how odd.

How's this setup holding up mate? I'm replacing my cat soon and this join is in sh*t state.

It's spot on mate . I still get the occasional blow from the olive joint to centre section end , but the manifold end is fine . It should outlast any Renault kit with it being all stainless and it's certainly hell of alot stronger .

gogs_101 · Nov 25, 2016

Won't end up looking like this then! Whoever installed this one last time around forgot the springs and the joints suffered!

Jesus, has that even got a gasket in it?

gogs_101 · Nov 25, 2016

If it ever had, it's long worn away so defo getting stripped down and starting again!

Looks a proper bodge job :astonished: . Doesn't look as if a gasket was ever fitted , just a nut and bolt . The parts I put a link up for should sort you out no problem , you'll just need to source a gasket . I already had one from a previous kit , although the old one wasn't actually that bad when I took it off .

leedsboy · Nov 25, 2016

Was going to say you should be able to see the gasket between the cat and manifold.

I recently replaced mine with the genuine renault kit, not a difficult job just a bit fiddley. Get some glasses of goggles or something though if you do it on your drive, I got much rust in my eyes when I did mine which was far from ideal.

gogs_101 · Nov 25, 2016

Cheers for the heads up on that!

I've managed to source a second hand cat from a user on here, so hopefully fitting up week after next. It's just gotta get through MOT in dec then might go down the decat route.

State of current cat just for everyone's entertainment:

Only bought the car in October and already pumping money into it as it's been neglected for too long [emoji15]

And I thought mine was bad. I'm fitting a decat this weekend and then getting my old cat sleeved for MOT time.

MRBILLYUK · Nov 25, 2016

I'm gonna look at getting mine sleeved next year sometime . I wouldn't bother fitting a decat . I had one , it did bugger all. Only increased the noise of my Yozza . I took it off when it was due its MOT then sold it.

I'm sure we've had this convo in another thread not long back. I need to get my cat sleeved properly as it's drooping badly and causing it to blow. Decat was £25 so thought I'd hear how it sounded for that price and at least I can drive it whilst the cat is getting done.

Yeah I vaguely remember that conversation . I can understand why you want to try it then . Did you buy a new centre exhaust hanger ? That'll help support the centre section .

Surprised this kit didn't attract more attention, ive fitted near enough all of the components above and the joint is so much stronger and saves having to continually replace with the full kit. Top work and appreciate all the advice

bearne1 · Feb 18, 2017

Managed to get the full kit fitted today and used a 2.5" donut gasket from my local motor factors for £3.

Pictures added to show the results.

R3k1355 · Feb 20, 2017

2.5" wire ring gasket fits perfectly you say??
Good news :up:

Sure does, search for PGG30

bearne1 · Feb 20, 2017

I followed MRBILLYUK's advice and went for the M8 75mm bolts and locking nuts with his custom made spring 'cups'. You can easily use the original cups and just drill a bigger hole to slide over the bolt but it doesn't look great. The whole setup is then much more durable and only £3 for a gasket rather than £22-£30 depending on your dealer cost for the whole fitting kit which are very weak.

What springs would you use with this? I'd use the ones on my kit, but the springs are both different...

I used the original springs from the Renault kit , they were the only part that hadn't rusted . Maybe you've bought a kit in the past from northwest performance and the springs are slightly different ?
These look the same as the Renault springs , but obviously i can't say 100% for sure or vouch for their quality.

It's a PO who has bodged my cat fitting kit. One side looks like a genuine spring, the other looks like one that was lying around. Cheers for the link. I think i'll just go genuine though for now.

bearne1 · Feb 21, 2017

Pretty sure the genuine kits are the same from Peugeot but much cheaper.
