BMW F95 X5M Catless Downpipes – Straight-Pipe Design for Maximum Flow, Horsepower Gains & Aggressive Exhaust Sound | Fits F95 X5M with S63B44T4 4.4L Twin-Turbo V8 Engine (2019–Present)

Unlock sharper throttle response, faster spool, and an aggressive, motorsport-inspired tone with the BAVMODS® Dual Catless Downpipes, precision-engineered for the BMW F95 X5M equipped with the S63B44T4 4.4L Twin-Turbo V8.

From the factory, the X5M’s exhaust system is restricted by two high-density catalytic converters that trap heat and create unnecessary backpressure — limiting turbo efficiency and power output. The BAVMODS® Catless Downpipes eliminate those restrictions entirely, allowing your twin turbos to breathe freely, spool faster, and deliver a deeper, more aggressive exhaust note worthy of an M badge.

Engineered for Maximum Flow, Power & Sound

Built from high-grade T304 stainless steel and TIG-welded for unmatched durability, these catless downpipes are engineered to withstand extreme heat and pressure. Each downpipe is mandrel-bent for a perfectly smooth interior surface — maximizing exhaust velocity while minimizing turbulence and backpressure.

Key Performance Benefits:

• Dual Free-Flow Design: Eliminates restrictive factory cats to unleash both turbochargers.
• Faster Turbo Spool: Boost pressure builds quicker and sustains longer across the rev range.
• Massive Power Gains: +35–55 HP and +50–70 lb-ft torque when paired with a Stage 2 tune.
• Aggressive Exhaust Tone: Deep, resonant idle with sharp pops and crackles under throttle.
• Reduced Heat Soak: Lowers exhaust gas temperatures, improving turbo and engine longevity.
• OEM+ Fitment: Direct bolt-on using factory O₂ sensor placements and stock mounting points.

Complete Plug-and-Play Installation Kit

Everything you need for a precise, clean installation is included — no cutting or fabrication required.

Includes:

• Dual stainless-steel catless downpipes (left & right turbo outlets)
• Pre-drilled O₂ sensor ports
• Premium clamps, gaskets, and mounting hardware

Pair with a Stage 2 ECU tune for maximum performance and proper CEL (Check Engine Light) management.

Why Go Catless?

The catless downpipe setup is the most effective upgrade for unlocking the full potential of BMW’s S63 twin-turbo engine. By removing the restrictive factory catalytic converters, you:

• Free up exhaust flow for quicker turbo response
• Reduce backpressure and thermal load on the engine
• Improve exhaust tone and turbo whistle clarity
• Unlock tuning headroom for higher boost and increased power

It’s the single most effective upgrade for enthusiasts looking to make their F95 X5M sound and perform like a true super SUV.

Performance You Can Hear and Feel

From cold start to redline, the BAVMODS® Dual Catless Downpipes completely transform the X5M experience. Expect instant spool, crisper throttle response, and a ferocious tone that commands attention whether on the street or at the track.

Your S63 deserves freedom — not restriction.
