MINI Cooper JCW GP3 Mk3 F56 3" Downpipe - Cobra Sport UK Made 200 Cell Sports Cat or Decat (De-Cat) Turbo Front Pipe | High Flow Stainless TIG Welded Performance Exhaust | Stage 2 Turbo-Back Upgrade

Unlock the full potential of your BMW MINI John Cooper Works GP Mk3 F56 with a high flow front section designed to transform response, tone and performance. Crafted by Cobra Sport in the UK using precision TIG welding, this front pipe is the go-to upgrade for enthusiasts who want faster turbo spool, stronger mid range acceleration and a deeper motorsport soundtrack.

Available in two configurations to suit your build and usage, both created in large bore 3 inch 76.2 mm pipework for exceptional gas flow and minimum restriction.

• 200 cell sports catalyst 4.5 inch 114.3 mm canister for high flow while retaining a catalyst, ideal for power gains with a refined sound and pronounced overrun character.
• Straight through decat for maximum flow and the most aggressive exhaust note, aimed at track, competition and off road use.

Why this upgrade is a must for your JCW GP

• Bigger, freer flowing design 3 inch 76.2 mm tubing reduces back pressure and helps the turbo breathe, setting the stage for significant power and torque improvements when combined with supporting mods and calibration.
• Sound you can feel deeper, more purposeful tone with crisper overrun crackles that suit the GP3’s character.
• Precision UK build designed, manufactured and tested in Sheffield, the heart of the UK steel industry, with beautiful TIG welds and quality you can trust.
• Direct fit engineered to join to the factory system or pair with a Cobra Sport cat back to create a complete turbo back upgrade.
