The IE Catted Cast Downpipe for MQB incorporates the best of all worlds. Cast bend sections enable the highest flow and best fitment possible. Impressive performance gains will be realized when used with an IE stage 2 ECU tune. Lastly, the aggressive sound from an unrestricted exhaust system is guaranteed to be music to your ears.

  • Proven performance gains for Stage 2 power levels

  • 76mm (3 inch) tubing replaces restrictive 60mm factory tubing

  • Bolt on fitment - no hassle or poorly fitting parts when you choose IE

  • Constructed of 304 stainless long-lasting and high-quality material

  • Thick turbo flange - prevents leaks and warping

  • High flow 200 cell catalytic converter - full power without the smell

  • Metal matrix catalytic structure

  • OEM style flex section - allows for more adjustment and wont fail

  • All inclusive kit - downpipe, midpipes, all hardware

  • TIG welded construction - equates to long-lasting welds that are less likely to fail


An aggressive and drone-free sound will be emitted from the IE Cast Downpipe. This should be music to your ears! Thick wall tubing and cast sections remove much of tinny sound emitted by cheaper, thin wall, downpipes. With downpipes, you get what you pay for in terms of sounds and overall manufacturing quality.


IEs performance downpipe includes a high-flow 200 cell per inch metal matrix catalyst located as close to the turbo as possible. Metal matrix catalysts are higher performance because the matrix web is thinner, allowing higher flow in the same size. Our catalyst is also a very large diameter, allowing a large flow area and maximum power. By being placed close to the turbo, emissions and unwanted unpleasant smells are greatly reduced.


The IE downpipe replaces over 6 feet of restrictive factory exhaust tubing, all the way back to the OE Cat-Back rear section. Sturdy fabricated mounts and precise engineering result in a rattle free and long last replacement exhaust system. 3D scanning systems were employed to ensure perfect placement both in pre and post-production phases.
