Features & Product Details

If you are wondering what mods can you start to perform to your newly acquired turbocharged vehicle, then an upgraded downpipe could be one of the answers from the masses. But not just any downpipe, a quality downpipe. COBB Tuning has developed a Performance Bellmouth Downpipe which is the result of extensive testing, and design to develop the consumer on the quest for more horsepower. This downpipe combines increased piping diameter along with smooth mandrel bends that produce more power by improving throttle response and reducing turbo lag. 

This downpipe has been fabricated from high-quality 304 stainless steel and comes with a high-flow catalytic converter implemented in the design to remain environmentally friendly.  

This is a direct replacement and direct fitment downpipe in place of your factory issued unit, and will come ready to install.

COBB Tuning Downpipe Bellmouth ( Part Number: 571202)
Much improved power 3 years ago
5out of 5stars

The factory DP is a beast to remove but is possible without a lift or pneumatic tools. That being said one you glimpse the factory cat it's amazing it breathes at all. This part significantly improves exhaust flow and response. I have a COBB Stage 2+ power package with this installed and it doesn't disappoint. Be aware that you may encounter the smoking turbo after install due to bad seals in the factory K04. (This may have been happening already, only the factory cat was catching and burning off the excess oil as to not be noticeable.)

  • Q: CEL  mikehawk2427 years ago

    will this throw a CEL?

      A:  Technically because this downpipe does change the flow characteristics of the exhaust it is possible that it will throw a check engine light. We do recommend having the vehicle re-tuned with the Cobb AP which will help optimize power and take care of the check engine light. That being said we have had customers install this without a re-tune and have seen both results.
