CityBug Decat Manifold Fitting Guide + Tested / Catalyst Replacement Installation (C1/TAygo/107)

[@infidelcastro5129]

That stripped M10 bolt into an M8 nut using an M9 tap & die is genius 😊 Thanks.

[@StupidBlokeStupidVideos]

You’re very welcome ☺️

[@barryrogers9862]

Just Thank you for what you do it's always entertaining, long live the shitroen

[@StupidBlokeStupidVideos]

Thanks mate, that’s good to hear.

[@JAYG6390]

Nothing like a greased up flange. YES!

[@StupidBlokeStupidVideos]

YES!

[@mariabutler3356]

Nice one. I'm thinking of getting a piper manifold as well for the Aygo. But now you mentioned hollowing out the stock cat, that might actually be a good idea and save a few quid. To pass the local MOT I'll just get a universal sport cat and install it somewhere in the middle

[@StupidBlokeStupidVideos]

I’ll just put a cat back on for MOT. Now it’s been off it should be easy to do even without taking the bumper off

[@AC-um2mk]

Love the steam train sound effects 😂

[@StupidBlokeStupidVideos]

🤣

[@Dazg-666]

I was going to get one of them piper decat manifolds don't think I will bother now lol.outstanding video though keep the good work up.

[@StupidBlokeStupidVideos]

Cheers mate. The difference isn’t huge but is there, it’s mainly at higher revs. It’s been on a couple of weeks now and actually feels slightly more flat at low revs and seems to use a little more fuel too. The sound is definitely better though, it does make it louder which I didn’t really want but the note is better.

[@nootybobs]

Love your videos 👍

[@StupidBlokeStupidVideos]

Thanks!

[@shingerz]

Cracking video esp the end lol 😆 👍👍

Enjoyed this, SBSV! Idea for a future project: I decided I want to paint my current shitter C1 and have been watching about 18 thousand YT vids on painting cars with rattle cans. Some turn out like a polished pig and some pretty shockingly good. So there you have it! First a bit Karate Kid ("Sand'a car, Daniel-San") to roughen the clear coat for adhesion, and then you don't even need primer if you use an enamal paint (like Rustoleum) or a nice matt acrylic (like Autotek). PS.. Bright yellow is said to be the best colour for rattle cans - can barely see imperfections and naturally blends between section. I'm going matt black though. Go for it..... I dare ya!

[@StupidBlokeStupidVideos]

Cheers mate. I’m shit at bodywork but the sill on the other c1 actually turned out way better than I could have ever expected. If you’re painting onto paint you just need to scotch the surface. Matt black is one of the easiest colours not to show imperfections too as there’s no shine to reflect off them, where as gloss black is probably the worst for it lol. Good luck.

[@schmittalain]

Hello your videos are great can you tell us where to buy all the parts and where to find a reinforced clutch. Thanks

[@StupidBlokeStupidVideos]

@@schmittalain thanks mate. I got the manifold from a lad on the CityBug club on facebook. It’s a really good group full of helpful people. As for clutch, not sure about reenforced but I fitted a Blueprint one which are usually decent.

[@schmittalain]

@@StupidBlokeStupidVideos Thanks

@@StupidBlokeStupidVideos Thanks

[@GTiR23]

Just to demonstrate my far superior knowledge, the ring end of the 22mm spanner WILL fit over the connector plug of the lambda sensor so you don’t slip off using the open ended side and batter your knuckles

[@StupidBlokeStupidVideos]

It does, I think I got it through first time I removed it when I spunked oven cleaner into the cat to clean it

[@ShaunBourke]

Very jealous that yours isn’t leaking I haven’t been able to find a way to stop my piper manifold from leaking at the flange currently got 2 gaskets and a sealant all around it and it’s still leaking

[@StupidBlokeStupidVideos]

Did you see how I sealed it? The gasket needed spacing off to seal on the shitter

[@ShaunBourke]

@@StupidBlokeStupidVideos yeah I’ve got a custom exhaust with a wider centre pipe so I don’t even have one like that in mine

[@StupidBlokeStupidVideos]

@@ShaunBourke ohhhhh, just weld a short flex to the shitter then 🤷‍♀️

[@thesilentgametestr]

Forgot how long geared these cars are, been awhile since I've owned a 107, but that's a good pull in 3rd. Mine was model with a rev counter, can't remember what the redline is, but for a 5 speeder you were near top speed in just that one gear. I never used to rev mine out like that, so the mighty 1ltr bug impresses me more.

[@StupidBlokeStupidVideos]

They’re just major powerhouses 😂

[@shackwishprice6924]

Kepp up good work great vids love it

[@StupidBlokeStupidVideos]

Thanks mate!

[@mikeallan7814]

One question,iam not sure but have you already remove the catalyst from inside of the manifold ( the old one ) before you take it out to put the new one? If yes did you see any difference in performance? Thank you for your nice videos even with one hand!!👋

[@StupidBlokeStupidVideos]

Hi mate, yes the cat I removed was already hollowed out. The difference after fitting the Piper wasn’t that much to be honest, a bit more power higher up the rev range but is actually a little bit worse at lower revs and seems to use a little bit more fuel as a result. It’s also a bit louder/more raspy than before.

[@onepalproductions]

If this can give me more mpg, I'd give it a try. Thanks for sharing. 👍

[@StupidBlokeStupidVideos]

After a couple of weeks living with it, the mpg seems to have dropped by about 3 😞

[@elliotpollard9083]

@@StupidBlokeStupidVideos shouldn't make much difference because at 1000-2000 RPM, even at full throttle, you're only creating 1/6-1/3 of the gas at 6000 RPM. Maybe gave a few extra hosses though

[@Dark-Lord3386]

When you going to fit a supercharger kit?

[@StupidBlokeStupidVideos]

Maybe one day, finding the time that’s the issue

[@davidlaw899]

Did it go through the MOT ok without a Cat?

[@StupidBlokeStupidVideos]

@@davidlaw899 nope, every year I have to refit a catalyst to get the shitter through test. Tbh it’s not worth the hassle

[@standard_ad9408]

I’m interested to know what sorta mpg your getting after all the mods?

[@StupidBlokeStupidVideos]

About 37mpg all round town, but I could get more if I didn’t have big dumb heavy feet. Before any mods I used to get about 43 on the same journeys.

[@chrisyboy219]

It seems a little bit faster at the end comparison - and you had more fuel on board, so I reckon it's made a difference. Pretty slight though, hey?

[@StupidBlokeStupidVideos]

Yea I’d say you’re bang on. It is slightly quicker, but as a downside it also seems to have lost a tiny bit of grunt at low revs. It seems to have moved the torque curve higher up the rev range a tiny bit.

[@chrisyboy219]

@@StupidBlokeStupidVideos maybe a higher top speed now! 😁

[@thesilentgametestr]

​@@chrisyboy219you can hit 105 on the speedo in stock form and not going down hill either.

[@StupidBlokeStupidVideos]

@@davydbot3496 nah, remapped out. Tbh I never got one even before mapping it out even after I moved my o2 sensor to the engine bay and have an obd HUD which potentially was automatically clearing the fault 🤷‍♀️

[@LabFan369]

Have you had an MOT with this setup yet ? or the gutted cat setup ?

[@StupidBlokeStupidVideos]

Nah, I couldn’t get anyone to MOT it with a Decat unfortunately. Seems that the DVSA are a lot more strict on it than they used to be

[@LabFan369]

OK, so how did you get it MOT'd ?@@StupidBlokeStupidVideos

[@StupidBlokeStupidVideos]

@@LabFan369 it was a ball ache. I had to borrow a catalyst and fit it temporarily to get emissions readings.

[@dadb251]

how about a yaris gearbox conversion with lower final drive

[@StupidBlokeStupidVideos]

I’d consider it maybe one day

[@thomaswykes3647]

[@TheYeminator]

Hi Tim, what do you do when its MOT time? Will it pass with that on?

[@StupidBlokeStupidVideos]

Hi mate. It won’t pass with a decat unfortunately. Last MOT I had to borrow a scrap catalyst and refit for the test. Pain in the dick tbh, but only took 10 mins to fit as all the bolts were free due to being off recently.

[@TheYeminator]

I’m replacing mine at the moment for my MOT next week, pretty easy, and your video really helped

[@StupidBlokeStupidVideos]

@@TheYeminator glad it helped! Thanks for watching, and don’t forget to have a look through my other vids 🤣

[@boulton455]

​@StupidBlokeStupidVideos silly question mate, but any idea what size the bolts are? It seems the 4 manifold bolts are 12mm? What about the cat? Are they 12s as well? Im just trying to get all the tools organised before i whip the bumper off. Thanks mate

[@StupidBlokeStupidVideos]

Ah shit I can’t remember tbh. The bolts that go into the bottom of the cat usually knacker up and rust away tbh so may be worth getting a pair of new ones and new springs if possible

[@boulton455]

@@StupidBlokeStupidVideos ahh, thanks for the reply anyway. I've got all new bolts and springs in the post, and the bumper should be coming off tomorrow, So I'll find out what size they are tomorrow anyway. Loving the content by the way. Just got myself a 107 and been binge watching your vids. Great stuff 👍

How do you run your C1 on reserve?! As soon as mine hits 2 bars I have to fill it up 😂

[@StupidBlokeStupidVideos]

I always run it down to reserve as it’s my marker to work out mpg lol

[@userbasba]

Good idea m8, but haven't you broken many emissions laws by getting rid of the catalysator?

[@StupidBlokeStupidVideos]

Probably just about all of them.

[@jojoletoucan5722]

​@@StupidBlokeStupidVideosshit on ! 😂

[@Monbleydonraces]

My 107 has no subframes on or doors or bonnet or seats. If the doc considers me fit to drive it might be one out come if not it will be a different one and I’ll need a clown suit to satisfy the locals who take the P cos they think I’m nuts. But as a lightweight (possible!) who will be the clown?

[@StupidBlokeStupidVideos]

I took the doors fully off this in one of my early vids 😂

[@bazmondo]

You need a remap to get the most out of the manifold, at least an extra 15 BHP will be unleashed.

They aren’t road legal I wouldn’t fit one as they cause pollution. I don’t have kids so there isn’t their health to worry about. I told my insurance in the eighties I’d put different manifolds and a straight through silencer and a bigger carb on my Austin Mini they said it won’t make any difference- it was about 4 miles an faster at top speed than the standard one I overtook eventually 😂😂😂😂. On a disused airfield of course where I later nearly caught a non genuine police car at 105 miles an hour in the same Q plated Mini😂😂😂😂
