WG9725540198 HOWO Exhaust Pipe

The WG9725540198 HOWO exhaust pipe is a key exhaust system component for HOWO heavy-duty trucks including tractors, cargo trucks and dump trucks. It discharges engine exhaust, reduces noise and optimizes airflow to maintain engine performance, lower fuel consumption and meet emission standards.

Made of premium materials with precise workmanship, the pipe body adopts high-temperature-resistant 304 stainless steel with corrosion and heat resistance. The flange is made of high-strength Q235 carbon steel for high pressure resistance and durability. The sealing gasket is high-temperature-resistant graphite with good sealing and anti-deformation properties.

With fully original-matched mounting size, bolt holes and length for HOWO vehicles with WP series engines, it requires no modification for direct installation.

It endures 600℃ high temperature, 2–500Hz vibration, rainwater and salt fog corrosion without deformation, cracking or air leakage.

Simple installation: no bracket adjustment or pipeline cutting needed. Just remove the old part, install the new pipe with matching gasket, fasten bolts and check for leakage.

All products pass strict pre-shipment tests: air tightness (0.3MPa leak-proof), 48-hour 600℃ high-temperature resistance and vibration resistance for stable reliable performance.

Product Model: WG9725540198

Applicable vehicles: HOWO A7/T7H/T5G (original HOWO exhaust system, matching WP series engines)

Type: Exhaust pipe (304 stainless steel + Q235 flange + graphite gasket)

Function: Guide exhaust, reduce noise, optimize flow, maintain engine performance

Material: Pipe body (304 stainless steel, high-temperature resistant); flange (Q235 carbon steel); gasket (high-temperature graphite)

Installation: Direct replacement-fits original exhaust interface and bolt specs

Working conditions: -40℃~600℃; ≥0.3MPa pressure resistance; 3mm pipe wall; ≥300,000 km life

①High-temperature & corrosion resistance: 304 stainless steel pipe + high-temperature graphite gasket withstand extreme exhaust temps and harsh environments, ensuring long-term stable use.

② Smooth exhaust & low noise: Optimized pipe diameter and curve reduce exhaust resistance, improve efficiency by 25% vs ordinary pipes, and lower noise by 15-20dB.

③ Perfect for HOWO: Made to HOWO's original exhaust design-installation interface, bolt spacing, pipe length match. No adapters or pipe cutting needed-saves 30% maintenance time vs universal exhaust pipes.

④ Durable & reliable: Thickened 3mm stainless steel pipe wall enhances impact resistance, high-strength flange ensures firm connection. Works stably in complex roads and long-distance driving-lasts 300k+ km.

This Exhaust Pipe (Model: WG9725540198) is only for HOWO heavy-duty trucks-A7, T7H, T5G models with original HOWO exhaust systems (matching WP series engines). It won't work on HOWO with modified exhausts or other brands (FAW Jiefang, Dongfeng Tianlong). Those have different exhaust structures, interfaces, or engine displacement needs-this exhaust pipe won't fit or work.

Q1: Works on HOWO with modified exhaust systems?

A1: No-modified exhausts have different structures/flow requirements. It causes mismatched installation or poor exhaust, leading to power loss or higher fuel consumption. Get the exhaust pipe for modified HOWO exhausts instead.

Q2: Exhaust noise increases or leaks after install?

A2: First check gasket installation (no deviation/damage). If good, check flange bolts (tighten evenly). If tight, check for pipe deformation (avoid collision during replacement). Still faulty? Replace the pipe (rare defect).

Q3: How to maintain the exhaust pipe?

A3: 1. Check flange connection and gasket for leaks every 30k km (replace gasket if damaged); 2. Clean pipe surface often to remove carbon deposits/dust/corrosion; 3. Inspect pipe body for deformation/cracks during maintenance-replace if damaged.

Q4: Need to replace exhaust manifold gasket with new exhaust pipe?

A4: Not mandatory but recommended. New exhaust pipe works best with intact manifold gasket-old ones cause exhaust leakage. Inspect manifold gasket and replace if worn for optimal performance.
