Buell kits at a glance

Find your model's row to see which silencer line goes on it and what it replaces. A slip-on swaps out the factory silencer (muffler). A DB killer (baffle) sits in every Buell kit and is removable, and the slip-ons add the link pipe.

Cone or round?

Powercone Evo is cone-shaped, hand-brushed 304 stainless steel. Deeptone Inox is round and made of 304 stainless steel. A given Buell takes only one of them.

The line is already decided, so the choice that remains is the kit type. The 1125R and 1125CR mid-line system is the one Buell kit marked not compliant, and GPR suggests a professional fits it. For a Buell ridden on the street, the slip-ons are the simpler choice.

Buell questions

Which kit goes on a Buell XB12?

The Deeptone Inox double slip-on. It swaps out both stock silencers and ships with its link pipes. The XB9 uses the same kit.

Why is the Ulysses XB12X listed twice?

One listing starts in 2003 and the other in 2008. Both are Powercone Evo slip-ons, so go by your bike's year.

What does the 1125 mid-line system take off?

It removes the original mid-pipe and silencer. No structural changes are needed, though GPR suggests a professional fit.

Which Buells take a double slip-on?

The XB9 and the XB12, both with the Deeptone Inox kit.

Does a Buell kit come with its link pipe?

The slip-ons do. A DB killer (baffle) sits in every kit and it is removable.
