- Please Note, Fitted after the next ride videos were recorded. A bit confusing, but YT, is taking forever to process large files at the moment.
First ride after fitting the Hitchcocks De-cat pipe. Only a short video, just to see how Clementine felt. Have to say, as you can tell in the video, I am mightily impressed. - บันเทิง
Clementine’s Looking good and sounds fabulous, worth it for the sound alone 👍
She does sound naughty, but looks normal 🤭😂
Wow sounds fabulous Ian love it👍🏻
Just need the rain to bugger off so I can get out again 🙄😂 cheers
Hi , glad it has worked out ok and worth the money ,just a very happy chap . Ride safe and enjoy .
I am, thank you.
Totally agree with you I switched to a hitchcocks decat exaust on my 500 bullit also fitted dna filter and also fitted an ngk plug performance vastly improved and boy what a sound just love it
Definitely, has to be done 😁
absolutely bloody smashing mate, sounds brilliant. 👏👍
Thank you, appreciate that 😎
I approve of that mod' Ian. It sounds superb. Worth it in smiles/GBP.
Definitely 😎
Sounds great, it really does, and a lovely road too
PS, lovely tickover!
Cheers, it made all the difference in feel and I can now hear the gentle burble. Lovely ☺️
Yours is the one I'm buying in the spring. 👍
Excellent, it’s decent quality 👌
Splendiferous, just enough and not too much 😊
Yes, sounds bob on now. Cheers
Or "cock on" as we say here in these parts 😂👍
I got a de cat pipe in with my Red Rooster exhaust from India. But, now we get charged import tax fee.
These are already proving to be cracking engines.
Bruce of Coastrider Scotland has nearly 12k miles on his. He be putting the cam in, this weekend.
I do like the sand signals version, but seat too high for my short legs.
😅
@weemark67 I follow Bruce. I am considering saving up for the cam, but YT will have to pay for it, so it may be a while 😭🤣
@@ianhughesroyalenfield 😂😂😂😂
Nice one Ian, she now sounds like the classic 500....
Yes, definitely a deep throaty burble now. So happy ! Cheers
The previous owner of my Sportster put a set of pipes on her. Louder than stock but not too loud.
Just an excellent bike saw a classic 350 in the flesh the other day in Hebden red and chrome on just looked great and yours sounds really nice Ian good move there I think 👍
Thank you, the sound was ok before, but bob on now.
FuelX pro is the 1to go for,can customize your mapping to suit your after market parts upgrades, going to get very lean with de cat pipe and filter
Maybe one day, I have just gone for the open air filter cover for now.
Nice to know you can feel the difference and it’s not offensively loud. I’m likely to do the opposite and start with the DNA filter/cover kit and see how it goes. I think the airbox is more restrictive than the exhaust, and I don’t necessarily want a louder or catless pipe anyway.
You might be right. I wanted a slightly louder sound, but needed to retain the looks of the original. The DNA filter will have to wait a bit now, as too many other things are stripping my banking account 🙄😂. From what others have said, you will notice an improvement 👍 cheers
I agree ive tried just uncovering the OEM filter and that made a huge difference.
However I like the silencer but not the Cat as imho its like the OEM filter and restricts the gas flow .
Yup, hence why I did the de-cat. I also fitted the open filter cover, with original filter, but have since put original filter cover back on, as the induction roar was giving me a headache on longer rides. Tbh, there is very little difference between open intake and original snorkel. Fitting a DNA filter would obviously make a bigger difference. I have considered fitting a DNA with original snorkel but funds are too tight just at the moment to go experimenting.
Yes, I am interested in seeing how the DNA with the snorkel goes but everyone is into the stage 2 so that data isn't as readily available, if you do so in the future please do a video showing your findings 😊
@TatisAcunaJr I did remove the original snorkel, and use an open one, but with the standard filter (there is a video elsewhere on my channel). Induction roar was greatly increased, so much so, that I put the original one back on for longer rides, as it became annoying. I didn’t really notice much difference in feel, though I have no doubt that a DNA (stage 2 is just the filter and open cover) kit would give a minuscule amount of increased performance. Cheers
Clementine sounds good.
Much better.
Swapped the filter for a DNA one with the open intake on my Meteor 350. Then replaced the collector box and cat with the same Hitchcock pipe. Sadly I had a small leak where the down pipe meets the dect pipe... So all off this morning and used a little exhaust paste and all sounds well! Just need to swap the centre stand as the early Meteors relied on the collector box to act as a stop.
Can't wait to ride it! I have heard that it can make the fueling a bit lean, not sure if that is so. I let it run for 10 minutes on tickover after installing the air filter and again after fitting the exhaust, so fingers crossed!
I found that leaving about a quarter of an inch of gasket, proud of the decat pipe, then clamping up, prevented the gasket from leaking, and also shooting into the decat pipe 🙄. It was too late to put in this vid. Bruce, CoastRider Scotland, has recently fitted a fuel x lite, and rates it. He too has a straight through pipe, dna and open intake. youtube.com/@coastkid71 it might help. Cheers
@@ianhughesroyalenfield I wanted to do that and every time I pushed the clamp onto the pipe it would push the gasket back into the pipe. This morning I discovered that the original clamps have a little 'tooth' that is responsible. So I got the dremel out with a small grinding wheel and cut it off! Worked a treat - probably didn't need the exhaust paste after all....
@@pauld7827 so you didn’t use the supplied clamp then. It replaced the original.
@@ianhughesroyalenfield Thought I could just use the original! Doh!
@@pauld7827 ahh ! It didn’t help with there not being any instructions 🙄. Easy mistake to make. As was mine, to have the gasket flush with the decat pipe, then have it shooting inside when I was 30 miles from home 😂. Hence my suggestion to leave the gasket out by 1/4 of an inch.
Sir did you keep the silencer stock? I wish you had made a before & after video for the sound comparison.
Hello, this is a video I did before changing to the decat pipe, maybe it will give you an idea th-cam.com/video/Y7fPmtUNk1s/w-d-xo.html and yes I have retained the original silencer as I wanted Clementine to look standard. Thanks
Ian, is there a part No: for the De-cat, as I cannot find it on the Hitchcock website? Thank you!
I just went onto their website now, go to shop by model, Classic 350 REBORN, and it came up.
@@ianhughesroyalenfield oh I see! so it must be a "Reborn" exclusive I guess, I'll go check it out again, thanx Ian. 👍
No problem.
Did you also upgrade the air filter to a DNA filter and opened end? If not give us your thoughts when you do so. Thank you
No, not yet. One for the future, maybe, but she runs and sounds sweet enough as she is. Coastrider Scotland, has a straight through exhaust, and open DNA kit. He fly’s around on his Classic 350, and loves the way it feels. He has also fitted a 16 tooth front sprocket. Here is a link to his channel, you could mention that I pointed you in his direction 😉. Cheers

Tec Bike Parts have vlog on the FuelX lite etc it's worth a look.
Brilliant, thanks, I will have a look.
was looking at this but i have the stealth black model will the stock heat shield fit back on??
Yes, that is why I went for this rather than some cheaper options. 👍
Just bought a Classic 350 and fitted a Hitchcock’s de-cat to my bike. Was going to add the Hitchcock’s free flow air box cover (keeping with paper air filter) but decided against this after hearing of increase in induction roar. Having compared the standard air filter cover and the “free flow” cover I have concluded that there is no difference in the intake hole size into the filter and my opinion that the snorkel actually draws air into the filter almost by turbo effect. I didn’t buy the bike for massive performance so will stick with de-cat only. It does sound a lot better and helps the bike lose a little weight in the process.
Quite agree Keith. I fitted an open air box cover, but the induction roar was really annoying on long rides, so put the original back on. The tone from the exhaust is “just nice” now, sweet, without being offensive. Cheers
@@ianhughesroyalenfieldDid you have to re-educate the ECU again when you switched back to standard air box setup?
@keithholyoake322 I did let Clementine idle for about 10mins. I know some say it's a waste of time, but I do it anyway.
I think that’s very wise and I will do the same tomorrow when I refit the standard air box cover. I’ll have a coffee while it is sorting itself out. The (very large) workshop manual is quite clear on doing so (that’s idling the bike, not having a coffee)! Cheers!
@keithholyoake322 😂
Luv this Ian, Clementine sounds lovely. Just be carfull of over zealous pigs if the pipe is not for road use.
Ride safe
Neil
They won’t be able to see it, as the original cover is still in place. Looks bog standard 😎 cheers
@@ianhughesroyalenfield Way to go man🏍👍
Hi Ian, Super sound, interesting you saying it's improved the performance, I bet a matching re-map would make even more difference? just wondering, will you have to re-fit the original in a couple of years when it needs an MOT?
I love the sound of the Classic 350. I've fitted a 75mm heatproof rubber pipe through the rear wall of my shed which pushes on to the exhaust of my Classic 350, so that it can tick over in the shed without it ( and me) breathing in the exhaust fumes. The sound coming out of the back of the shed is amazing, much deeper than normal, the whole back wall acts as a sounding board, and of course there's no engine noise.
I like your shed exhaust extractor, sounds like heaven 😂 As for having to refit the cat, I am unsure, but I guess it depends on the testing station. If it needs refitting, it doesn’t take too long, though might need a couple of new gaskets. Worth it though. I think the Fuel X thing I was talking about would help more so. Cheers
@@ianhughesroyalenfield I don’t think Cats are tested on motorcycles so if this correct you should be ok. But, whadda I know🤪
@@mrgrizzlyrides that’s kind of the way I was thinking, but unsure. Hmm, I think I may know someone, I will ask. 👍
Just had confirmation from a motorcycle technician friend ; motorcycles are not tested for emissions, or whether a cat is fitted. It could however, fail if excessively loud compared to standard.
What sort of fuel consumption do you get from the shed and is it safe at motorway speeds ? 😀
reat video Ian , I'm thinking of getting one, is it much lighter??
Actually not as much as I had hoped, due to being made from quality stainless steel, unlike the original. I did consider weighing them before fitting, but forgot 🙄 sorry.
Is it euro legal then ? Could one be fitted to a meteor 350 euro 5
My Classic 350 is a euro 5. Hitchcock’s do a different one for the Meteor. Runs fine !
Hi Ian you can definitely here the difference in sound be the best mod the DNA filter on both my bikes you can here the roar of the induction sound they make brilliant 👍👍👍🙏🙏🙏
I have the K+N equivalent on Honour, but they don’t do one for the Classic 350 yet. Cheers
@@ianhughesroyalenfield nice your feel and hear the difference once fitted 👍👍🙏
Hi planning to decat as well on my 2023 RE Classic 350. Did you have to do anything else to the bike with just removing the cat? Thank you.
Good afternoon. No, just remove the old, and replace with the decat. If you buy the Hitchcock’s one, I would suggest just leaving a quarter of an inch of gasket proud of the decat at the downpipe (header) end, then clamp up. This prevents any chance of the gasket shooting inside the decat pipe (yes this happened to me). The only other thing I did, was once all fitted, just start the engine, NO REVS, and leave to idle for about 10 minutes to allow the ecu to acclimatise, then switch off, before being good to go. Some people say you don’t need to do this step, but for the sake of just 10mins it is worthwhile, even if it doesn’t do anything 😉 Oh, and the bracket on the decat, goes the outer side of the frame bracket, not the inner. Hope this helps, but if I can be of anymore help, please just ask. All the best 😎
@@ianhughesroyalenfield
Thanks for your quick reply! I will order the pipe from Hitchcocks asap. Did you notice that the bike runs cooler, and did the fuel economy change. Thanks again!👍
@mr2bmw hmm, not noticed it run cooler, and I have never checked mpg, as it does lots to the gallon, I just top up as and when. Certainly not noticeable.
If you watch some of my latest vids, you can really hear the gorgeous sound under load (up hill), and the hilarious pop pop pop on the overrun (down hill) 😂 Bloody brilliant 😉
@@ianhughesroyalenfield
Thanks again, I have subscribed...I will watch them all!😄
Curious if you could explain the "short" bit? I'd hate to buy a part that is not properly sorted and I end up with a funky mod...
Thank you and,
Ride Safe 🙏🏼
It was hard to explain whilst riding, so ; at the bottom of the downpipe (header pipe), there is a flange, which the original cat butts up to. When fitting the de-cat, it is “short” by about a quarter of an inch. This doesn’t matter, as when the supplied gasket is fitted and the supplied clamp is fully tightened, no gases escape. I only mentioned it, because I noticed it when fitting. When you replace the original outer shield, you don’t see it. The reason I went for the Hitchcock’s de-cat pipe, is that it is the only one I could find, which has the mounting points for the original outer shield. Basically, it look’s completely standard. Hope this helps, and feel free to ask if you need help with anything else.
@@ianhughesroyalenfield Cheers, Ian! I figured that was what you meant.
Not only does it maintain the guard, but it’s stainless and the Indian pipes on eBay are junk steel. Since Hitchcock sold out of them, I am hoping the new batch might address that issue.
Supposed to be in stock coming February.
Thanks for the quick reply and the always great videos!!
Ride Safe 🙏🏼
@@scottboettcher yes, I forgot about that but. I did look at those Indian ones, but they really did look crap 😂. 🤞 you get sorted soon. Glad you enjoy the vids, cheers.
@@ianhughesroyalenfield did you not look at the red rooster exhaust from India?
@@kevindarkstar not too keen on a lot of the stuff from over there. I prefer the look of the original, and definitely prefer quality parts, especially as I ride the 350 through winter. Don't want something that is going to be rusty afterwards.
I did air filter and that made a difference. Do you still recommend de cat ?
I haven’t changed the air filter yet, so I wouldn’t like to recommend. I know of others who have, in conjunction with the the decat, without any issues. My only fear, is that the bikes run lean before we start making them breathe better. Some have fitted the “Fuel X” device, which is supposed to sort out the fuel/air mixture, but there are mixed opinions as to whether that actually does anything, rather relying on the ecu to adapt. Bruce (Coastal Rider) has a dna filter, and a straight through exhaust amongst other modifications, and loves it. He doesn’t ride slow either ! You could fire a quick question to him. Here is a link to his channel : youtube.com/@coastkid71
@@ianhughesroyalenfield thanks for the reply. I'll continue to watch your adventures. A perfect little bike 👍
Brilliant, thank you. I am just editing a new video from a ride yesterday. It will hopefully be uploaded later today.
Has fitting the exhaust made your warranty void?
Don’t know, but if anything happened, it would be easy to swap it back to standard 😉
@@ianhughesroyalenfield Thanks Ian. Ride safe.
Any damage on engine till now??
No, absolutely fine. Retaining the original silencer, means it is not straight through.
Did u keep stock silencer???
Yes 👍
Thanks for subscribing 😁
Any mileage drop or troque drop or engine problem
I haven’t noticed any change in miles per gallon (but I don’t scrutinise that, when it’s low, I refill). No change in engine characteristics, other than feeling a bit freer. All the oomph is still there, and we do ride in the hills, with some steep gradients (just have a look at my ride vids). No engine problems what so ever. After fitting, I did allow the engine to idle for 10 minutes to acclimatise the ecu. Some say it works, some say it doesn’t, but in my opinion, I can happily wait 10 minutes before revving 😎.
@@ianhughesroyalenfieldoh boy!! Just decat today! Sound so lovely and she finally breathing! Mine is halycon green!! I only waited for 5 minutes and thanks for detail reply!
Excellent, happy to help.
It's the rev limitation that's built into the ECU that's causing the restricted performance, unless someone can come up with a by pass for this filters and exhausts will be of limited value 🙄
Very true, but they sound sweeter, and have a slightly better response off the throttle.
You get that stage 2 on the airbox and you will probably be able to cruise on the motorways and not feel like it's taxing the engine.
That would be good, but as I don’t really do motorways, I just want Clementine to have a bit more “get up and go” on the lanes, and B roads. Cheers
@@ianhughesroyalenfield in that case my friend you're on the right track, the dna performance air filter and the hickcocks decat pipe is exactly what you want, as to the fuel X I'm not sure if it's really needed, as the ecu adapts to the air flow and at the price of the unit I'd advise you to fit the dna first run it for a while see what you think 👍🏻
@@kevindarkstar I agree, having watched other reviews on the Fuel X, it probably doesn't offer much. I have a few things coming up needing my money, but hopefully at some point, I will get the DNA. I was hoping K+N bring one out, as it would be cheaper, and do the same job. I have one of those on my Interceptor. Thanks for the comment.
Pros and cons of de-cat?
No cons with the decat. Sound is just nice, small weight saving, retains look of original exhaust, engine feels slightly peppier.
@@ianhughesroyalenfield no mileage drop will occur ryt?
@@90gen26 acceleration feels slightly better. Too speed unaffected. As you have possibly seen, I bought the stainless steel decat from Hitchcock's. Other cheaper ones either don't fit right, or rust.
@@ianhughesroyalenfield I'm from India so can I get any decat for my bike or any suggestions?
@@90gen26 I am in UK. I do believe there are companies in India who make them, but you will have to do your own homework on that, sorry I can't help.
I do enjoy a bit more pop n fart out me back end!
Great little bike!
😂 Addictive isn’t it 😂
And if you'd have bought exactly the same pipe from India (which is where Hitchcocks get theirs) as I did it would have cost you £23.00 with free delivery.
Really ? In stainless steel as this is ? I have heard people buying from India, and receiving mild steel. Do you have a link to share with everyone who might be interested ?
@@ianhughesroyalenfieldI am from india I can not get stainless cheaply anywhere!?? But instead I got normal steel 9 dollar only
Unfortunately, with our climate and salt/grit roads here in the UK, mild/normal steel would rust like crazy 😢
@@ianhughesroyalenfieldcan you make comparisons between ours and old 500 !!? It would be great
@rachitanandhiremath2234 unfortunately, I haven’t yet ridden the 500. Maybe one day, I will get the opportunity. I have had an offer to ride one owned by a subscriber, but it’s a case of timing.
How to make your bike pollute more!
Whatever 🥱
Will you shutup and drive...😅
With this attitude, fuel engines will soon be banned.
What are catalytic converters made for?
Apparently you have no children or grandchildren.
