UM Motorcycles exhausts and decat pipes for the 125 DSR

Which UM 125 DSR do you ride?

Two models, three year sets. Look up your bike in the left-hand column, then compare the year in each listing's title.

Model	Year sets	Kit types	GPR lines
125 DSR SM / EX	Two: bikes from 2018 and bikes from 2021	Slip-on (link pipe included) and decat pipe	Albus Evo4, Furore Evo4 Poppy, Furore Nero
125 DSR Adventure TT	One: bikes from 2018	Slip-on (link pipe included) and decat pipe	The same three lines

Three silencers, one choice of finish

• Furore Evo4 Poppy: stainless steel with a carbon-look finish in matte black, weighing 1.8 kg in the listing.
• Furore Nero: black aluminum under a ceramic finish, matte black as well, with the same 1.8 kg weight.
• Albus Evo4: ceramic-treated aluminum in glossy white, 1.75 kg (3.86 lbs).

Each slip-on stands in for the stock silencer (muffler). All three are oval and 350 mm (13.8 in) long, and each ships with a link pipe, CNC-machined Avional end caps and a DB killer (baffle) you can remove. They differ by color, not by fit, so the finish is the only thing to choose. Albus Evo4 is the only white one, and its listing shows 50 g less than the other two.

A decat pipe for each year set

Every year set also has a GPR Decat Pipe. The pipe is 304 stainless steel and sits where the catalytic converter was, with no catalyst in the box. Each listing labels it a race product and gives 1.1 kg (2.43 lbs) and no DB killer. The listings add that the pipe works alongside the stock silencers or GPR ones. See the whole range in GPR Decat Pipes.

No UM Motorcycles listing carries an EPA-compliant class. The slip-ons and the decat pipes are all labeled not compliant with EPA/CARB certifications.
