Exhaust Land Rover Defender (2020-Today)

The Land Rover Defender diesel models feature a Diesel Exhaust Fluid (DEF) tank with a capacity of 20.7 liters, applicable to Defender 90 and 110 regardless of the diesel engine selected. The exhaust system is equipped with a Diesel Particulate Filter (DPF) integrated within the system. The fuel tank capacity for diesel engines is 89 liters. Gasoline engines like the P525 V8 and P425 have specific performance features and braking systems that influence exhaust functioning.

The Defender 90 offers engines such as the P525 V8 with 0-100 km/h acceleration in 5.2 seconds and the P425 with 5.6 seconds acceleration. The Defender 110 features the P525 V8 engine with 0-100 km/h acceleration in 5.4 seconds. The engine bore/stroke of the P525 V8 is 83.0 / 92.31 mm with a compression ratio of 15.5:1, affecting exhaust characteristics including catalytic converter design and efficiency.

The Defender gas engine models with the P525 V8 have high-performance brakes with ventilated discs: the front brakes are monobloc calipers with 6 opposing pistons and 380 mm discs, while the rear brakes are floating single-piston calipers with iEPB and ventilated 365 mm discs. These braking systems influence exhaust heat management and vehicle performance modes.

Several curated aftermarket exhaust options provide unique sound and performance enhancements:

• QUICKSILVER Stainless Steel Line: Designed for the Defender OCTA 110 P635 V8 2025 model, this FAP-back valve system offers a sporty sound with perfect integration.
• COBRA SPORT Stainless Steel Line: Made from TIG-welded SUS-304 stainless steel for the Defender 110 V8 P525, this system delivers a notably muscular and sporty exhaust sound.
• BRITPART Replacement Downpipe: Available for Defender 90 and 110 models with reference NTC4426.

Additionally, performance modifications like a decatalyser for TD4 models increase power and torque by about 10% over the factory exhaust.

Upgrading your exhaust system can offer several benefits:

• Enhanced sound quality tailored to your preference.
• Potential improvements in engine performance and power delivery.
