In general, the basic components of a motorcycle are not the optimal or top-of-the-range products, also to meet the production and cost needs of the manufacturer, who tries to reach the right compromise between design, performance and final result. If, on the other hand, you replace a large double steel exhaust system with an aftermarket titanium unit that features a single silencer, you can achieve immediate weight savings of up to five per cent of the bike, with all the advantages in terms of handling and handling. performance. Furthermore, as mentioned, the aftermarket systems reduce sound emissions, so as to save the hearing and concentration of those who use the bike for long distances. And, finally, there is the possibility to choose the piece that best suits our taste, even aesthetic.
These replacements can have direct effects on the engine and performance, particularly with regards to its efficiency. The mufflers, in fact, improve fuel pumping, reducing the work of the engine to expel exhaust gases, particularly if they have improvements to the flow of air and fuel on the intake side.

ADVICE FOR MOUNTING THE AFTERMARKET EXHAUST ON UM DSR 125 EX
Here is a practical guide on some tips relating to the assembly and disassembly of a new exhaust for your UM DSR 125 EX although we always recommend that you contact a mechanic for the installation and choice of an exhaust for your UM
WHAT YOU NEED If you don’t have it, buy an unlocking spray, which costs between 5 and 10 euros: it will make your life much easier; same thing for the spring puller – in case it is not included in the box – but if you do not have it, you can use a pliers. Prepare 3/8 socket wrenches and 12-14mm wrenches. Finally, if you have it, a wire brush.
BEFORE BEGINNING Before starting to disassemble the original exhaust, make sure that all the parts are in the box: check that nothing is missing, otherwise you will have to stop the work halfway
When you are ready, place the motorcycle on the stand – or on the lift stands – to start disassembling any parts (such as the passenger footrests) that may hinder you in disassembly. The process can vary according to the various types of exhaust, the indications we give you are related to any type of terminal, but specifically we will talk about the side exhaust terminals, the most common on today’s motorcycles.
BE PATIENT Unscrew the clamp at the base of the drain. Due to its position close to the wheels, it may be slightly rusted and therefore difficult to unscrew. Do not use brute force, but help yourself with the unlocking spray. If you still cannot unscrew the nut, try loosening it by turning it in both directions. After unscrewing it and thus loosening the clamp, remove the exhaust attachment on the footboard or rear support, then rotate and pull the terminal towards you without being too abrupt. Again, if you can’t remove it easily, use the unlocking spray. After some effort, the terminal will detach from the manifold fitting. At this point we advise you to use a wire brush to remove the residues on the manifold attachment.
REDO THE SAME STEP To install the aftermarket exhaust, perform the same process in reverse. If you have problems inserting the new terminal, help yourself again with the unlocking spray or with the “svitol”. Fasten the clamp firmly to the base of the exhaust, while if there is a “vice” support to fix the terminal to the rear platform, tighten without exaggerating. If you do not have a spring tensioner to mount the safety springs, use pliers but being careful not to damage anything. Finally, check the tightness once more, if necessary when starting the bike check that there are no leaks in the base of the terminal.buy the suitable exhaust for your UM DSR 125 EX
