Royal Enfield Himalayan 450 Gets LOUDER! D-Cat Link Pipe Install & Sound Test!

[@jonathanmellish4439]

Remember that decibels go up in a logarithmic scale so its considerably louder.

[@magaudion]

When I’ve fitted a decat pipe to a bike in the past it’s made more difference than fitting an end can and makes the bike run much leaner so the bike needs to be remapped .

[@thatbikersimon]

Yes I agree all my bikes have had a re map but they have been performance bikes, i still need to test ride it so il let you know 👍

[@larifari4371]

Wich bike was that?

[@marktorbay]

Hi Simon, I've still got the 411 and it came with a, Lextek can which sounds so sweet over 3000 and I'm now going to do the decat but will do the full Delkevic s/s including downpipe but not can so should save even more weight. I've been told to reset the ecu, start and leave idling for 15 mins. Thanks for the video, enjoyed watching 👍 and happy New year to you and the Mrs

[@thatbikersimon]

Thanks Mark, it’s great to hear about your install, that’s interesting about that reset. I’ve not riden the bike since the new d-cat which was only yesterday, so I’ll hopefully bring some updates to the channel asap 👍

[@crystalpipic772]

I installed a "PoweRage SS silencer with header bend pipe" shipped from India via eBay. Very nice quality, relatively low price, and fast shipping, and the pipe has a very sturdy center stand stop as well as a vertical brace welded to it. The muffler is stainless and the same length as the OEM. It has a removeable dB killer. With the dB killer installed it is a bit louder and deeper than either of the bikes in your video - but not too loud, IMO. Total weight savings 5 lb. I might have removed the center stand as mynxl did if I'd thought of it. 😁

[@thatbikersimon]

That’s sound good, there’s a few good choices out there. I’m not sure if the centre stand will become a problem now, I not riden it since the install.

[@DaveOasist]

Im thinking of getting the PoweRage silencer for my 450 Gorilla too.

[@JaxsRacingGarage]

Great video, looking forward to the performance and how it hold itself on the bike.

[@thatbikersimon]

Thanks, me to I’m not expecting to much from it but I thought I’d See what it was like for such a cheap upgrade. The last time bought a link pipe it was for my Ducati Streetfighter V4s and cost me a fortune

[@isaacscamander]

Thanks for the info, cheers 🍻

[@thatbikersimon]

No problem 👍

[@mynxl]

I ditched the centre stand at the same time as fitting the decat. Temporarily refit it for servicing. Quite pleased with the result

[@crystalpipic772]

Interesting idea. When you temporarily reinstall the stand do you bother with connecting the springs? That's usually the hardest part.

[@thatbikersimon]

The centre stand does add some serious weight to the bike, and it not well balanced. It’s a question of if you don’t need it remove it. 👍

[@mynxl]

@crystalpipic772 Springs are not needed if just servicing the bike. Make sure to put the split pins in the pivots or risk the pivot pins falling out when lifting. Been there done that.

[@crystalpipic772]

@@mynxl Looks like I'd have to remove the link pipe to remove the right side pivot pin because there's not enough clearance to pull it all the way out. But it looks like to temporarily reinstall the stand that pin could be put in from the other direction so the pipe wouldn't have to be removed to get it out.

Have u seen himme 750 spy pic ?

[@crystalpipic772]

The resonator box has bumpers on the bottom and when you remove it the center stand is hanging free. Although in the video it kind of looked like the foot of the stand on the right side is touching the muffler. Your friend's bike looks like it had the center stand removed. Thanks for taking the time to do the video.

[@thatbikersimon]

Thanks for the comment, and yes your right my friend has removed his centre stand, the stand is hitting the left side swing arm. When i take it off the centre stand. You can buy de cats with a buffer on them. I’ve just put a rubber mount on the swing arm to see what happens. I’ve not riden the bike yet since fitting this, so il do a up date soon. 👍

Nice work !! Happy new year

[@TheNorthWestRider]

Have you looked at the AEW slip on at all? Considering that along with the decat pipe, seems to have a nice sound from the online content.

[@thatbikersimon]

I’ve not looked at any others my buddy was getting one, so I said get me one to. So it was a spontaneous purchase. I might have a look at others out of interest

[@bbt1627]

I've watched so much of your content I assumed I had subscribed, so apologies but I've liked and subscribed now. As always great video with clear instructions. Any chance of a link for that link pipe please.

[@thatbikersimon]

Hi, thanks for watching. My buddy ordered it for me when he ordered his so I’ve just messaged him to send me the link. Il drop it in the comments when he does, the only thing I’ve not taken into consideration is the centre stand, there’s a link pipe on eBay that has a bumper stop and I’m not sure if that’s needed or not as I’ve not test the bike yet. As a example this is a another link I’ve found www.ebay.co.uk/itm/375557861058?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=het-dljftlu&sssrc=4429486&ssuid=d7YjCDQITMC&var=&widget_ver=artemis&media=COPY

[@bbt1627]

@thatbikersimon thanks pal

[@mark.e.p]

I was told by an RE dealer that it invalidates your warranty? It's worth checking out. Although bikes don't need a CAT for an MOT.

[@thatbikersimon]

It’s always worth asking the question. I’ve fitted all sorts of cans and pipes to my bikes over the years. I wounder if RE do a after market exhaust. Its funny because Ive seen a Himalayan 450 under 10ft of water and RE covered the engine under warranty.

[@timcarmack8351]

Interesting graphics on the tank on the Hanle bike! Do you know where those were sourced?

[@ogasi1798]

certainly worth doing for the weight but defo for the sound, get yourself a better silencer as they do rasp quite nicely once changed

[@larifari4371]

Don't you have frequent tec inspections required by law to keep it on the road? Or do you just put the cat back in for those?

[@thatbikersimon]

We have MOT inspection every year in the uk (once a bike is 3 years old) A dealership has to sell it with a cat on it by law, but most will have an aftermarket exhaust option that they will sell you, and a remap it to the ECU, which they will fit once you own the bike. They don’t test for emissions on motorcycles when have a MOT

[@jeffrogers2180]

Wouldn't it make more sense both for power and emissions to change the muffler instead?

[@thatbikersimon]

Well changing both would make more sense but it would probably be realy loud

[@stevereilly]

Does the decat not reduce backpressure thereby causing engine damage and voiding the warranty? It's a Euro 5 so I always wondered if this was the issue (my Triumph 1200 scrambler was worse without the cat.

[@thatbikersimon]

Interesting question, I don’t think will make any impact on the engine, I’ve never had any problems with any bikes with warranty problems when swapping end cans and exhausts. Maybe that’s question for the dealership.

[@mark.e.p]

Normally, the ECU resets itself.

[@ogasi1798]

no

[@philipcooper8297]

4 stroke back pressure is a myth.

[@tin_man9]

Just so u know cat is actually in the pipe where the pipe changes sizes but eliminating resonator box does change sound and weight but your cat is still in their

[@crystalpipic772]

The official RE service manual identifies that box as the "cat box" so it must be more than simply a resonator chamber.

[@tin_man9]

Cat is in the pipe

[@larifari4371]

Maybe two cats? One in front and one in the box? For Euro5 a small pipe cat only will not do.

[@tin_man9]

Dont know didn't see anything in the cat box I do know the cat is in pipe further forward

[@adkomst]

Hi. Interesting to watch I enjoy your vids. Thanks. But are d-cat pipes legal? Would it get through an MOT with a d-cat fitted?

[@thatbikersimon]

Yes and no, I’ve never had a problem getting a bike though an MOT when a exhaust or link pipe has been fitted.

[@michielvandepol6765]

Yes, make it louder. So motorcycle-haters have even more reasons to complain. 77db or 85db is a huge difference. Db's are logarithmic. Thanks a lot, mate. Kind regards from all bikers that try to keep roads open for motorcycles.

[@larifari4371]

It wasn't very precise measuring but still more of cause. But not not badly loud either. The crazy louds are the problem, not those returning to noise levels of 5 or 10 years ago.

[@thatbikersimon]

It’s not made much of a difference, I rode it yesterday and it was probably the quieter bike on the road. You don’t sound like a motorcycle enthusiast.

[@moherhat]

Does the ECU compensate for better air flow and lean mixture? KTMs 390s have problem with that - changing exhaust usually causes rough throttle due to lean mixture

[@crystalpipic772]

I've done the de-cat and replaced the OEM muffler with a somewhat less restrictive one and haven't noticed a bit of difference in throttle response, acceleration, starting, or idling. The only difference I've noticed is that it's a bit louder and deeper.

[@thatbikersimon]

Yes I agree I’ve been and rode the bike today and not noticed any difference apart from sound

[@backontwowheels9469]

That does sound better and there might be a minute power increase, as to whether it is noticeable remains to be seen. I think my first upgrade will be bark busters, maybe some folding mirrors too, as I am sure I will need them lol. I am still disappointed about the crash protection actually damaging the tank with one drop, I mean what is it meant to be protecting?

[@thatbikersimon]

I need to get the handguards aswell (bark busters are great) , I think the link pipe is not going to increase the power but who knows, I’m considering a ride tomorrow 1st jan 2025. Il hopefully have some feed back. Happy new year buddy 👍

[@thatbikersimon]

Why not? When a motorcycle in the uk has a mot it’s not tested for emissions, it’s only has to be sold with a cat to meet legal requirements, my insurance isn’t affected. Most other dealerships will offer a aftermarket exhaust option after sale.
