300TDI Defender and Discovery Front Down Pipe (No Catalyst)
Upgrade the exhaust system on your Land Rover Defender or Discovery 1 300Tdi with this high-flow, catalyst-free Front Down Pipe (Part No. ESR3495SS). Designed to eliminate the restrictive factory catalytic converter, this component improves exhaust gas scavenging, lowers exhaust gas temperatures, and helps unleash a more responsive throttle and improved turbo spool.
Manufactured from durable stainless steel, this down pipe is built to withstand the harsh elements and heavy-duty off-road use, preventing the corrosion and sagging common to standard steel factory pipes.
Key Features
- Catalyst-Delete Design: Removes the restrictive OE catalytic converter to optimize exhaust flow, improve engine efficiency, and slightly enhance turbo spool-up.
- Full Stainless Steel Construction: Premium-grade stainless steel build provides exceptional resistance to rust, corrosion, and high exhaust temperatures.
- Direct Bolt-On Fitment: Engineered to match original factory routing and flange positions for a straightforward installation with standard exhaust gaskets and hardware.
- Improved Durability: Replaces failure-prone mild steel factory components with a heavy-duty, long-lasting alternative.
Vehicle Compatibility
- Land Rover Defender: 300Tdi models (1994–1998)
- Land Rover Discovery 1: 300Tdi models (1994–1999)
- Range Rover Classic: 300Tdi models (1994–1995)
Technical Specifications
- Part Number: ESR3495SS (Stainless Steel Equivalent)
- Application: Turbo Outlet / Front Exhaust Downpipe (Non-Cat)
Workshop Tip: When replacing exhaust components, always install a new turbo-to-downpipe gasket and fresh mounting nuts/studs to ensure an airtight seal and prevent exhaust leaks under boost.
