( number of products: 1 )

Upgrade your BMW X7 with premium performance downpipes. Choose from catted or decat downpipes to increase power, improve turbo spool, and achieve an aggressive exhaust tone.

BMW X7 Downpipes – Unlock the True Potential of Your Luxury SUV

The BMW X7, introduced in 2018, is BMW’s flagship luxury SUV, combining cutting-edge technology, premium comfort, and immense power. Despite its impressive stock performance, the OEM exhaust system – especially the downpipes – restricts your engine’s full capabilities. Upgrading to performance BMW X7 downpipes is one of the most effective ways to boost horsepower, improve throttle response, and enhance the overall driving experience.

Why Upgrade to Performance BMW X7 Downpipes?

The factory downpipes are engineered for emissions compliance and noise control, which limits exhaust gas flow and reduces turbo efficiency. Installing performance downpipes transforms your BMW X7’s character:

  • Significant horsepower and torque gains – optimized exhaust flow unleashes hidden power.
  • Faster turbo spool – enjoy quicker throttle response and sharper acceleration.
  • Enhanced exhaust sound – catted downpipes deliver a sporty, refined tone, while decat downpipes produce a motorsport-inspired roar.
  • Lower exhaust gas temperatures – improve thermal efficiency under heavy load and spirited driving.
  • Perfect for ECU tuning – essential for Stage 1, Stage 2, and hybrid turbo setups.

Types of BMW X7 Downpipes

Our selection of BMW X7 downpipes is designed for various tuning levels and driving styles:

Catted BMW X7 Downpipes

Catted downpipes integrate a high-flow sports catalytic converter, offering the perfect balance between emissions compliance and performance gains. Ideal for daily-driven vehicles in regions with emissions testing.

Decat BMW X7 Downpipes

Decat downpipes remove the catalytic converter completely, maximizing exhaust flow and power output. Best suited for off-road applications, track use, or areas without emissions restrictions.

Material Options: Stainless Steel & Titanium

We offer BMW X7 downpipes in two high-quality materials to suit different needs:

  • Stainless steel downpipes – durable, corrosion-resistant, and cost-effective, perfect for most builds.
  • Titanium downpipes – ultra-lightweight, superior thermal performance, and premium motorsport finish.

BMW X7 Engine Compatibility

Our BMW X7 downpipes are compatible with a wide range of petrol and diesel engines across different variants:

  • BMW X7 xDrive40i Downpipes – optimized for the 3.0L B58 inline-six turbo engine.
  • BMW X7 xDrive50i Downpipes – designed for the N63 twin-turbo V8 engines.
  • BMW X7 M50i Downpipes – engineered for high-output V8 performance models.
  • BMW X7 M60i Downpipes – performance solutions for the latest mild-hybrid V8 powertrains.
  • BMW X7 M Downpipes – extreme-performance options for the S68 twin-turbocharged V8 platform.
  • BMW X7 30d / 40d Downpipes – high-flow diesel downpipes for torque gains and improved efficiency.

Performance Gains with BMW X7 Downpipes

Replacing restrictive OEM downpipes with performance BMW X7 downpipes delivers substantial performance improvements:

  • +25–55 HP with downpipes alone.
  • +70–120 HP when combined with Stage 2 ECU tuning.
  • Significant torque gains across the rev range.
  • Improved throttle response and reduced turbo lag.

Choosing the Right Downpipe Diameter

The correct downpipe diameter plays a vital role in maximizing performance:

  • 2.5-inch downpipes – ideal for mild upgrades and Stage 1 setups.
  • 3-inch downpipes – recommended for Stage 2 builds, hybrid turbos, and high-boost applications.

All our BMW X7 downpipes are designed for direct bolt-on installation, ensuring seamless fitment without cutting or welding.

Build Quality & Engineering

Our performance BMW X7 downpipes are manufactured using state-of-the-art techniques:

  • Mandrel-bent tubing for smooth and unrestricted exhaust flow.
  • Precision TIG welding ensures strength and leak-free operation.
  • High-grade stainless steel or titanium construction for superior durability.
  • OEM-style flanges and fittings for perfect integration.

Tuning Potential

Pairing BMW X7 downpipes with ECU tuning unleashes the engine’s full potential:

  • Massive horsepower and torque gains.
  • Optimized turbo efficiency and fueling strategies.
  • Custom exhaust sound profiles tailored for catted or decat setups.

Daily Driving vs Track Builds

For daily-driven BMW X7 models, catted downpipes are the perfect choice, balancing performance and emissions compliance. For track-focused builds, decat downpipes deliver maximum flow, power, and an aggressive motorsport exhaust tone.
