DESIGN
BOLD. REFINED. ENRICHED
The iE ProCore Downpipe takes your VW MK8 GTI, Golf R, or Audi 8Y S3 to a new level of menacing. The high-flow 200CPSI catalytic converter is generously sized to support any engine tune and hybrid turbochargers. Our specialty in-house engineered precious metal coating process produces an advanced CAT to align with ECU emissions requirements, so you can upgrade without the check engine light for a triple win: high-flow design, no CEL, and plenty of ruckus to be raised.
WHEN LOUD ISN'T LOUD ENOUGH
GIVE IT ALL THE BEANS
Adding an iE catback exhaust system to your MK8 adds an instant punch of sound, fun, and character, but it doesn't have to end there. The factory downpipes are full of sound-deadening restrictions that hold you back from experiencing the full exhaust experience. If you find yourself wanting more, convert your iE catback into a true turbo-back with our 3" free-flowing downpipe and embrace the rowdy.
PROCORE ADVANTAGE
NO PESKY LIGHTS HERE
Our ProCore Catalyst features our advanced coating process, your secret sauce to passing vehicle readiness monitors. This precious metal coating is applied with an advanced molecular bonded wash process to ensure long-life reliability. Keep your barbaric sound intact and avoid that annoying check engine light.
HIGH-FLOW DESIGN
ELIMINATE RESTRICTIONS
Pass vehicle readiness monitors and still get the complete power, torque, and spool from your hardware and tuning upgrades. Our full 3" piping and large 5" 200CPSI CAT maintain optimal flow to support any power output up to large and hybrid turbochargers.
CUTTING-EDGE MANUFACTURING
THE FUTURE OF DOWNPIPES
There is a lot of smart thinking in design, materials and manufacturing that went into making the ProCore downpipe. It’s made of T304L stainless steel, investment casting for smooth transitions, and hand TIG welded using precise fixtures and tooling for a seamless, leak-free build. Our CAT design is a cutting-edge concept, formulated for meeting or exceeding emissions output without restricting flow.
