Royal Enfield models by engine family

Royal Enfield names bikes by displacement, so the table follows the numbers. Slip-ons stand in for the silencer (muffler) and come with their own link pipe, and most listings carry a removable DB killer (baffle) in their specs; the exceptions are named below the table.

Slip-on, Race, Decat Pipe and link pipe: what each one is

  • Slip-on: replaces the silencer, link pipe included. The listings say it goes on without structural changes.
  • Double slip-on: two silencers with link pipes, for the 650s and for the Deeptone Duplex on the 450s.
  • Race: comes without a catalyst. The Furore Nero, Furore Poppy and Ultracone Race versions also leave out the DB killer, while the Deeptone Race versions keep a removable one. GPR notes that a racing exhaust may call for an ECU remap.
  • Decat Pipe: 304 stainless steel, fitted where the catalytic converter sat, with no catalyst inside. Sold by GPR as a race product.
  • Cut-Box Racing Link Pipe: made of 304 stainless steel, for the 2024 Himalayan 450 and 2024 Guerrilla 450, with no DB killer.

The Himalayan 410 and the Scram 411 have the widest choice, and Satinox or Deeptone Inox is a good first comparison. The standard versions of both are listed for each bike, so you can compare them without touching a Race kit.

Royal Enfield buyer FAQ

How do the Himalayan 410 and Himalayan 450 kits differ?

They are different bikes with different kits. The 410 mostly takes classic-style slip-ons such as Trioval, Vintacone and Ghisa, while the 450 takes Satinox, Powercone Evo, Dune Triovale Titanio and Deeptone Inox, plus a double slip-on.

Is there a single slip-on for the 650s?

No. Listings for the Shotgun 650, Continental 650 and Interceptor 650 are all double slip-ons: one silencer per side, link pipes included.

Can I run side luggage racks with a 450 slip-on?

Check before ordering. The Satinox, Powercone Evo, Dune Triovale Titanio and Deeptone Inox slip-ons (Himalayan 450 and Guerrilla 450) carry a note that side racks for luggage cannot be used with them.

How does a Race slip-on differ from the standard one?

It comes without a catalyst, and the Furore Nero, Furore Poppy and Ultracone Race versions also omit the DB killer. The word Race appears in the listing title.

Which bikes have a Decat Pipe?

Classic / Bullet EFI 500, Scram 411, Himalayan 410 and Himalayan 450. It is installed in the spot the catalytic converter occupied and holds no catalyst.

How far back does the Royal Enfield range go?

The Classic / Bullet EFI 500 starts in 2009, the Continental GT 535 in 2014 and the Himalayan 410 in 2017.

What does the Cut-Box Racing Link Pipe do?

It swaps out the original link pipe, and only on the 2024 Himalayan 450 and the 2024 Guerrilla 450. The listing says no structural changes are needed, and GPR recommends a professional installer.
