Aston Martin DBX / DBX707 Downpipes — Catless, 200-Cell & 400-Cell High-Flow | M177 4.0L Twin-Turbo V8 | 2020+
YPG Motorsport race downpipes for the Aston Martin DBX and DBX707 replace the restrictive factory catalytic converters with precision-engineered, flow-optimized stainless steel pipes. The DBX707 uses the AMG M177 4.0L twin-turbo V8 — the same engine platform YPG has been building and tuning since 2011, and the same engine that powered the first sub-10-second C63 quarter mile in history.
The factory catalytic converters on the DBX sit directly downstream of the turbochargers, creating significant backpressure right where exhaust gas velocity is highest. Replacing them with aftermarket downpipes is the single highest-impact bolt-on modification available — unlocking faster turbo spool, sharper throttle response, substantial power gains, and a dramatically deeper, more aggressive V8 exhaust note with the burbles and crackles that the factory system suppresses.
Catless vs 200-Cell vs 400-Cell — Which Should You Choose?
Catless downpipes ($2,499) — Zero restriction. Maximum flow, maximum power, loudest and most aggressive exhaust note. Best for: track use, spirited driving, builds prioritizing maximum performance.
200-cell high-flow catted ($3,900) — Ultra-high-performance 200cpsi sport catalysts. Flow is within 5–10 HP of catless while substantially reducing exhaust smell. Best for: daily-driven DBX builds, enclosed garage parking, owners who want performance without the cabin odor.
400-cell GESI high-flow catted ($5,499) — GESI GEN2 400cpsi catalytic converters rated for 1,000+ HP. Closest to emissions compliance while still delivering meaningful flow improvement and enhanced exhaust sound. Best for: street builds prioritizing compliance alongside performance gains.

Installation
Professional installation recommended. The downpipes bolt directly to the factory turbo outlet flanges — no cutting, welding, or fabrication required. Compatible with factory exhaust and aftermarket cat-back exhaust systems.
An ECU calibration is recommended to eliminate any check engine light and unlock the full performance potential. YPG Motorsport offers Stage 1 and Stage 2 ECU tuning for the DBX / DBX707 M177 platform.
Why YPG Motorsport for Aston Martin
The DBX707 uses the same AMG M177 4.0L twin-turbo V8 that YPG Motorsport has been building and tuning since the platform launched. Our team holds the world record for the first sub-10-second M177 quarter mile — 9.97 seconds at 828 WHP, set at Beech Bend Raceway Park, Kentucky. We know this engine inside out. Every part we sell is a part we'd put on our own builds.

Frequently Asked Questions
Will aftermarket downpipes void my Aston Martin warranty?
Aftermarket downpipes are a bolt-on modification that can be removed and returned to stock at any time. Under the Magnuson-Moss Warranty Act (US), a dealer must prove that the modification caused the failure to deny a warranty claim.
Do I need a tune with DBX707 downpipes?
An ECU calibration is recommended to eliminate any potential check engine light from rear O2 sensor changes and to unlock the full performance potential. YPG Motorsport offers Stage 2 ECU tuning for the DBX / DBX707 — +130 HP over stock.
How much do Aston Martin DBX707 downpipes cost?
YPG Motorsport DBX707 catless downpipes are $2,499. 200-cell high-flow catted: $3,900. 400-cell GESI high-flow catted: $5,499. All options include free worldwide shipping and a lifetime warranty.
Will DBX downpipes trigger a check engine light?
Catless downpipes will trigger a CEL without an ECU calibration. 200-cell and 400-cell options are less likely to trigger a light, but a tune is still recommended for optimal performance and to ensure no warnings appear.
Is ceramic coating or heat shielding available?
Our downpipes come with heat shield wrapping included. Ceramic coating is available as an add-on — contact us for pricing.
