Types of exhaust (Silencer) for 350 / 500CC

Types of exhaust (Silencer) for 350 / 500CC

First & Foremost question which comes in all the Bull (Royal Enfield) Rider’s mind is “Which are the types of Exhaust Silencers (Mufflers) available in the market? And which is the best Exhaust Silencer for My Royal Enfield Model? Let it be Thunderbird, Classic, Standard or 350 CC / 500 CC.

Firstly let me make you understand “What Exhaust Silencer is?” And then we would classify all the after stock exhaust silencers in the board 3 categories along with pros and cons.

An Exhaust Silencer 

An exhaust is a series of pipes that links the engine to a silencer and a catalytic converter leading the burnt gas from the combustion chamber of the engine to outside. Exhausts have four main functions: to control noise, to direct exhaust fumes away from passengers, to improve the performance of the engine and to improve fuel consumption. 

Catalytic converter 

It is a vessel in the exhaust system containing catalysts like platinum, palladium, and rhodium; platinum and palladium convert harmful exhaust gasses by further oxidation of carbon monoxide and unburned hydrocarbons into water and carbon dioxide, and rhodium breaks the nitrogen oxides into nitrogen and oxygen. 

Types of Exhaust Silencers 

Absorption Type: The noise is absorbed by specific acoustical fibre inside the silencer. The Absorption Type silencer is most effective in the middle and high frequency range. These silencers are the least effective in reducing the thumps given off by the engine, which is what all of the Royal Enfield Bull Riders wants… Most of the after stock market silencers Goldie, Punjab, Indore, Rockets, Wild Boar falls into this category. 

Reflection Type: The noise is reduced by creating a gas flow through separate chambers in the silencer. This category includes aftermarket silencers made by Royal Enfield themselves for off-road riding (Upswept Exhaust) 

Reflection / Absorption Type: Silencers are based on a combination of absorption and reflection damping techniques in order to reduce the noise in the complete frequency range. This includes Exhaust Silencers used by the Royal Enfield in there new models (Company fitted) 

Details about Exhaust Silencers (Mufflers) available in Market for Royal Enfield

1. Upswept Exhaust: Designed for the classic 350 and the classic 500. It’s an after-market exhaust supplied by RE itself for off-roading purposes. Cost : NRI 2900 Approx
2. Goldstar Exhaust: A design made popular by BSA goldstar motor cycles. These exhausts also called Godie offer a deeper bass and better thumb. There are many varieties to choose from and even shorter versions are available. Cost : NRI 3500 Approx
3. Megaphone Exhaust: Megaphone exhausts are performance exhaust, which were initially made for the café racer .They are really loud but are not suitable for uphill or highway runs due to lesser torque provided. Cost : NRI 2500 Approx
4. Punjab Exhaust: Cheapest and loudest of all Exhaust, build based on the Absorption Type Silencers. An Indian made exhaust which tries to imitate the classic thumb almost to perfection. You almost can’t tell the difference. Cost : NRI 1800 Approx
5. Indori Exhaust: Another Indian made exhaust which tries to imitate the classic thumb almost to perfection. You almost can’t tell the difference. Cost : NRI 2300 Approx

Hope you would like the information on the different types of the Exhaust Silencers available for your Royal Enfield (Bull)

Happy Thumping

dirt bike by british customs

British Customs is a leading international supplier of Triumph-specific parts, accessories and gear – the market for Triumph parts has been growing exponentially in recent years and the Scrambler, Bonneville and Thruxton models have become cornerstones of the hugely popular cafe racer, flat tracker and scrambler sub-genres.
Rather than sitting on their laurels and focussing on product sales, the team at British Customs build their own bikes, often taking pre-existing Triumph models and tweaking them, as they did with the modified Triumph Scrambler you see pictured here.
The goal behind this build was to take the stock Scrambler and give it more off-road ability, the team at BC wanted a bike that would be as comfortable on dirt tracks as it is on the asphalt – making it the sort of retro dual-sport that would have been favoured by the likes of Steve McQueen and Paul Newman.
Starting with the boots, the exceptionally knobbly Continental TCXII 80 tires were chosen to enhance off-road grip in varying conditions. On the rear end a BC Retro Sprocket was added to reduce unsprung weight, new Renthal Fat Bars were bolted on to replace the stock bars, a new low profile 7” headlight was added, a new set of fenders were added front and back with the front unit mounted higher than stock, giving the bike a classic ’70s enduro look.
The full list of parts used on this bike is longer than your arm but if you’re interested you’ll find the full build package here courtesy of British Customs. If you’d like to see more of their builds, you can click here to see their full collection of customs.

The Musket Royal Enfield V-Twin

The Musket is the motorcycle that Royal Enfield should be building – or at very least the engine that they should have used in the the new Royal Enfield Continental GT cafe racer. It was designed from the outset to use as many stock Enfield parts as possible, with only the only significant new parts being the crank, exhaust and the engine case, the rest of the engine (and motorcycle) is built from original parts including the cylinders, pistons and heads.
This further convinces me that Royal Enfield need to buy the rights to this engine, then drop it into their ageing production line.
Originally designed and engineered by Aniket Vardhan, a native of India, the home turf of the Royal Enfield Motorcycles and a nation well-known for repurposing older technologies to keep them relevant and useable in the modern day. Aniket grew up like many Indian boys, love the putt-putt-putt of the antiquated single cylinder motorcycles pottering around the streets and alleyways of the subcontinent.
As he grew older he learned about the Harley-Davidson Motorcycle Company and their iconic V-Twins – a plan began to form and by the time he had moved to the USA to get his Masters in Industrial Design he had a well-formed idea in his head for a new kind of Enfield. An Enfield that would be twice as powerful, twice as loud and at least twice as much fun.


Aniket’s first attempt at the Enfield V-Twin was based on two 350cc engines, he created an entirely new crankcase and sandcast it himself. He was careful to over-engineer any new components and so with this in mind he made sure that the new crankcase was actually thicker and heavier than it really need to be – just to make sure it was the strongest link in the chain.
When he released his new 700cc Enfield to the world the motosphere lit up like a fireworks display over the Bikini Atoll, people all over the world contacted him with requests that he sell them one of his engines and the demand was such that he put the new V-Twin into limited production. Skip forward a couple of years to the present day and Aniket is well-known for building exceedingly reliable engines, as is always the case people wanted more power and so he’s been hard at work creating an entirely new engine based on two cylinders from the larger 500cc Enfield single.
The bike you see here is fitted with the new 59 degree, 998cc V-Twin and early reports indicate that it’s capable of over 70hp. Somewhat incredibly the new engine can be bolted into the frame of an original Royal Enfield Bullet 500 with only a slight bend in the top tube required to make it fit. The new engine with a slightly tighter angle between cylinders looks almost like the iconic V-Twin from the Vincent Black Shadow – perhaps not surprising when you consider that the Vincent engine was also originally constructed from two cylinders originally designed for a single cylinder motorcycle.

Triumph Bonneville

Triumph Bonneville Custom by Ton-Up Garage

The Triumph Bonneville has quickly become one of the most popular targets for motorcycle customisers worldwide, bikes like the Yamaha SR400, Honda CB750 and the Harley-Davidson Sportster have all previously held the title but the recent shift towards cafe racer/scrambler/flat tracker customs has benefitted the Hinckley-based motorcycle manufacturer to no end.
The custom you see here started life as a stock 2007 Triumph Bonneville, this model is becoming more popular due to the fact that it was the last year that Triumph fitted twin-carburettors – by 2008 the Bonneville and related models were all fitted with electronic fuel injection.
Dubbed Hiawatha after the Native American warrior, the Bonneville’s rebuild began with a teardown – during the reassembly process a new low profile seat was added and a new wiring loom was created to fit neatly under the saddle. The rear suspension was replaced with advanced Öhlins units and the front springs were changed to match. A new and much smaller speedometer was then added to new handlebars next to a slightly smaller front brake master cylinder, the handlebar-mounted switches were also replaced for smaller black units.
In order to boost engine response a new exhaust was added and the carburettors were re-jetted to match, new low-profile stop and headlights were also bolted into place above cropped fenders and 16″ rims. The finished bike has already been shipped to its new owner in Lisbon, it’s just about the perfect motorcycle for the ancient Portuguese city and apparently it can be heard hammering around the old cobblestone streets in the early evenings.

thing else is just that, anything else. It goes without saying

that we’ve worked hard for our reps and will do everything

in our power to maintain them. We do not apologize

for a damned thing. . .”

Sonny Barger, 2001- Hells’ Angel

I was a Hells’ Angel.”

“My husband (Steve McQueen) told me if I was ever stranded

on the side of the road, broke down, or in trouble, and if a club

member came by, accept their help. Trust them. Nothing

bad would come of it. They’d do me right. He even

went on to say that if the politicians ran the

country like the club ran its chapters, we’d

all be much freer. I think he liked their

Honor System and the fact that with

Bike riders, a hand shake was a

Hand shake, and a deal

Was a deal”

The World’s First Motorcycle

As you might imagine, there’s no small amount of controversy surrounding the invention of the motorcycle. In fact, some consider the first motorcycle to also be the first car – as it was created 2 years before Karl Benz unveiled his invention in 1886 and both were 3-wheelers propelled by a petrol powered, internal combustion engine.
Pictured above, the world’s first motorcycle is called the “Butler Petrol Cycle”, it was invented built by Edward Butler in England in 1884. It was powered by a 5/₈hp, 600cc twin-cylinder 4-stroke engine, with rotary valves, a float-fed carburettor and Ackermann steering. For those unfamiliar with Ackerman steering (as I was until I looked it up), it’s a method of steering that avoids the issues generated by 2-wheels on a fixed axle needing to travel different distances when turning – click here to read more.
The Butler Petrol Cycle is rear-wheel drive, interestingly its inventor didn’t see the need for brakes and so he didn’t fit any. Forward motion was stopped by raising the driven wheel off the ground via a foot-lever, transferring the weight to two castor wheels on either side. Whilst some consider Butler’s invention both the first car and motorcycle, it is generally agreed that it’s the first motorcycle. That said, it was pre-dated by a number of steam-powered motorcycles, so it all comes down to how you personally define what a motorcycle is.
