Silver Stallion Performance (SSP) Big Bore Free Flow Bend Pipe (Dual O2 Sensor Compatible) for Royal Enfield Classic 650

High pulling power.

The Silver Stallion BIG BORE BEND PIPE is a big bore free flow bend pipe for the Royal Enfield Classic 650. It is designed, developed and dyno tested by Silver Stallion Performance Pvt Ltd, also known as SSP, in Coimbatore, Tamil Nadu, and it adds 12% BHP and 7% torque over the stock system while weighing 3.1 kg.

Handles the increased exhaust volume of a free-flow can and gives a tuner something to work with.

What changes on the bike

• 12% BHP and 7% torque over the stock system, measured on the dyno.
• A larger bore that matches the flow of a free-flow can, so the slip-on is no longer choked by a stock diameter pipe.
• Pairs with a Silver Stallion slip-on to release the full 12 percent figure.
• Both oxygen sensor bungs are retained for stock ECU behaviour.
• Gives a tuner real headroom when the bike goes on a dyno.

Specifications

How it is built

Silver Stallion builds to a four stage process it calls the 4Ds: Design for airflow and shape, Detail in the welds and finish, Development for fit and durability, and Dyno to prove the numbers rather than claim them. Bodies are stainless steel, and every system is signed off on a dyno before it goes on sale.

How it sounds

A bend pipe alone changes tone more than volume. It deepens the note and removes the boxed-in quality of the stock pipe. Most of the volume change comes from the can you pair it with.

Is this the right exhaust for you?

It suits you if you ride the Classic 650, you want a real weight saving and a deeper note, and you would rather have a dyno figure behind the claim than a louder pipe alone.

Look elsewhere if you are keeping the stock silencer. The bend pipe is designed to work with a free-flow can and gives back little on its own.

Questions riders ask

Which motorcycles does the Silver Stallion BIG BORE BEND PIPE fit?
It is made for the Royal Enfield Classic 650. Send us your model and year before you order and we will help confirm the right part.

How much power does it actually add?
Silver Stallion quotes 12% BHP and 7% torque over the stock system for this big bore free flow bend pipe, measured on their dyno.

How much does it weigh?
3.1 kg, against a noticeably heavier stock unit.

What finishes can I choose?
Silver. All are priced the same unless the option list says otherwise.

Will it throw a check engine light?
No. This system keeps both oxygen sensor bungs, so the ECU stays in closed loop and reads the sensors as it did from the factory.

Can I fit the bend pipe on its own?
It bolts up on its own, but the quoted 12 percent gain assumes it is paired with a free-flow slip-on. On a stock can you will get much less of it.

Is this road legal in India?
It is an aftermarket performance part. Indian rules require a silencer that meets the noise limit your bike was homologated to, and enforcement varies by state. Check your local position before you fit it.

What does SSP stand for, and is it the same as Silver Stallion?
Silver Stallion Performance Pvt Ltd, based in Coimbatore, Tamil Nadu. The company is commonly abbreviated to SSP, and some dealers list the same parts under SS Motocorp. The range is designed, developed and dyno tested in India.

What warranty and support do I get?
Manufacturer warranty against manufacturing defects, handled through Rawtorque. Message us on WhatsApp for fitment help before or after you buy.
