carleef Diesel Heater Exhaust Pipe Kit 78.7" 1" ID Stainless Steel with Muffler — Flexible, Noise-Reducing Exhaust

This carleef 78.7" flexible diesel heater exhaust pipe kit is a corrosion-resistant stainless steel and aluminum assembly with a 1" ID hose and muffler designed to route exhaust, reduce noise, and fit tight engine compartments.

Whether replacing a worn heater exhaust hose or upgrading the exhaust path for a diesel heater installation, this complete kit delivers a long, bendable stainless steel tube, a compact aluminum muffler, clamps and mounting screws. The set is built to withstand heat, resist rust, and conform to confined spaces so you can position the outlet where it fits best inside a vehicle, boat, or generator compartment.

How does this kit reduce diesel heater noise?

The included aluminum muffler uses a porous internal layout and an S-shaped pathway to break up and dissipate sound energy, lowering the audible tone of exhaust pulses. A tight mechanical seal at each connection ensures exhaust is routed through the muffler rather than leaking, which improves overall noise control.

• Upgraded muffler internal structure for sound attenuation
• S-shaped internal tubing increases sound-wave resistance
• Clamps secure airtight joints to maximize absorption
• Pores and chambering diffuse exhaust pulse noise

Will the flexible pipe fit into tight or complex vehicle layouts?

The stainless-steel flexible tubing can be stretched and bent to navigate around brackets, bulkheads, and tight engine-bay geometries without permanent deformation. Its 78.74" length gives extra reach so you can route the exhaust outlet away from heat-sensitive cabin areas or toward a recommended discharge point.

• Flexible stainless construction bends to complex paths
• 78.74" length for extended routing options
• 1" inner diameter (ID) matches many diesel heater outlets
• Clamps included for secure, adjustable positioning

What materials and durability features does the kit offer?

The hose is made from stainless steel for rust resistance and high-temperature durability, while the muffler is aluminum alloy for lightweight corrosion protection. Together they create a corrosion-aware assembly suitable for long-term use in vehicle, marine, or stationary applications where heat and moisture are present.

• Stainless-steel tubing resists rust and heat damage
• Aluminum alloy muffler reduces weight and resists corrosion
• Quality clamps and screws provided for reliable joints
• Designed for repeated bends without permanent kinks

How simple is installation and what should I check first?

Installation is straightforward: remove the old hose, position the new flexible pipe and muffler, align the interfaces, then tighten the supplied clamps and screws. Before beginning, confirm the heater outlet matches the kit's dimensions to ensure a correct, secure fit.

• Step-by-step: remove old, position new, align, clamp, tighten
• Check pipe ID: kit ID = 1" (approx. 24–25 mm) for compatibility
• Muffler dimensions help confirm fit in mounting space
• Allow room to route hose without excessive bending stress

Who is this for: This carleef exhaust kit is aimed at DIY mechanics, installers, and owners of diesel heaters in cars, RVs, boats, and generators who need a durable, flexible exhaust routing solution with built-in noise reduction. If you require a corrosion-resistant hose long enough to reach an optimal discharge point and a compact muffler to lower exhaust noise, this kit provides the clamps and hardware needed for a reliable replacement or upgrade. Measure the heater outlet and available routing space before ordering to ensure compatibility.
