Product Description
The DZ9114545009 SHACMAN Exhaust System Muffler Pipe is a key part of the exhaust system for SHACMAN heavy-duty trucks (X3000, M3000S, F3000). It mainly reduces engine exhaust noise (cuts 25-30dB, meets GB 1495-2002 standards) and guides exhaust gas to discharge safely-avoiding scalding surrounding parts and ensuring driving safety.
We use good materials and professional tech to make it: the main pipe is 409L stainless steel, which resists high temperatures (up to 650℃) and rust (from exhaust condensation and road salt). The inner noise reduction layer has glass fiber cotton (withstands 700℃) and perforated plates, absorbing noise in multiple stages. The flanges at both ends are precision-stamped (flatness error ≤0.1mm) for tight fitting. Its installation dimensions (flange holes, pipe length, bracket position) match the original SHACMAN exhaust system. Replacement is easy: loosen old flange and bracket bolts, align new pipe's flanges, install bolts, and tighten to torque (flange 35-40N·m, bracket 25-30N·m)-no need to modify pipes or brackets. Before shipping, we test strictly: leakage test (no leak at 0.3MPa), noise test (≤82dB after install), 48h high-temperature test-quality is reliable.
Features And Advantages
Good noise reduction: 25-30dB cut, meets national standards.
Heat & rust resistant: 409L stainless steel, lasts 120k km.
Fits SHACMAN exactly: No modification, saves 40% time.
Leak-proof: Precision flanges + gaskets prevent exhaust leakage.
Application Scope
Only for SHACMAN X3000/M3000S/F3000 heavy trucks. No L3000 or Howo/FAW-different pipe diameter/specs, won't fit.

FAQ
Q1: Works on SHACMAN L3000 light trucks?
A1: No-L3000 has smaller exhaust pipes and flanges. Using it causes leakage and noise, so get L3000's special muffler pipe.
Q2: Exhaust leakage at flange after install?
A2: First check if the high-temp gasket is damaged/missing. If not, check if bolts are tightened to 35-40N·m. Still leaking? Replace the pipe (rare for new ones).
Q3: How to maintain?
A3: 1. Check bolts every 10k km-tighten if loose; 2. Avoid deep water to prevent internal corrosion; 3. Clean surface after cooling to avoid thermal deformation.
Q4: Need to replace high-temp gasket with new pipe?
A4: Yes, definitely. Old gaskets are aging-no replacement causes leakage, affecting noise reduction and engine power.
