9.5 Exhaust Pipes & Mufflers
Most current
URAL s use separate exhaust pipes (“headers”) for each cylinder, with a
separate muffler (“silencer”) on each side. Some models (e.g. Patrol) and earlier models
use a two-into-one system, with a single muffler on the right side. The two-into-two
system uses a crossover (“connecting”) pipe between the two mufflers. Both header
pipes and muffler are different for the two-into-one system.
To ensure Vehicle Emission conformance, correct carburetor function, safety, and engine
reliability, the stock
URAL

exhaust system must be retained and kept in good condition.
Mufflers which have become damaged, have rusted through, or have been modified will
effect engine performance, and should be replaced with stock
URAL

components to
avoid engine damage and violation of EPA regulations.
To remove the exhaust system
1. Undo the nuts fastening the passenger footrests and those of the engine front stud,
slacken off the clamp bolts, and remove the clamps (“clips”) from the stud.
2. Compress the rear suspension and remove the passenger footrests.
3. Take off the union branch pipe, spreading the mufflers ("silencers") apart.
4. Undo the clamping nuts and remove the muffler off the exhaust pipes.
5. Remove the ends of the exhaust pipes out of the cylinder head.
Reinstall the exhaust system in the reverse order.
Note: prior to tightening the muffler clamp nuts, pack heat-proof packing cord under
them (wood stove door seal material or muffler packing will suffice).
With the muffler attached and the header pipe in position, tighten the header clamp bolts.
