Features & Product Details

RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed. 

 

This is the GrimmSpeed Catted Downpipe. This downpipe is the result of countless hours invested in research and development to provide the performance consumer with a quality product guaranteed to deliver performance. This is a direct replacement of the OEM downpipe that is highly restrictive and leaves much room on the table for improvement. The GrimmSpeed unit combines smooth bends and a larger piping diameter to remove as much turbulence from the exit path of the turbocharger which will add more horsepower, and more torque while reducing the turbo lag. 

 

 

 

DETAILS:

  • 304 stainless steel construction
  • 1/2" thick 3D contour flanges
  • 3" piping diameter
  • 3D CAD designed to determine the contours and clearance from the firewall 
  • Divorced wastegate design for optimal flow
  • Designed with a secondary O2 bung for those adding a wideband O2 sensor
  • FARO arm design
  • Built-in high-flow 300-cell metallic substrate catalytic converter
  • Expertly TIG-welded
  • Includes new exhaust gaskets and hardware included for the installation 
  • Made in the USA
  •  

     

    NOTE:

  • Tune required for optimal performance
  • You will need to slightly adjust the divider tab to fit the V40/V46 turbocharger 
  • Please contact our customer service for further assistance

    GS continues to pump out great products, got it heat coated for extra heat absorption but ran into a fitment issue when running the Cobb 20G that's internally gated. The gate wouldn't fully open or close which resulting in crazy overboosting. Filled down the divider flap but still ran into problems so ended up going with a bellmouth DP. Highly recommend based on quality but make sure you know the clearances for IWG setups.

    The quality when I unboxed the downpipe was incredible. Every weld was perfect, the flanges are extremely thick and durable. The install was like any other downpipe install, very easy. I’ve had bellmouth downpipes that were difficult to get anything on the bottom but for the turbo flange but this wasn’t like that. As for the sound and performance, best downpipe I’ve had yet. I have it paired with a tomei Expreme catback and it sounds worlds better than my last STI that was invidia catless turbo back. Highly recommend this downpipe to anybody looking to stay catted. My car runs extremely well on the Cobb stage 2 OTS map as well. My AF ratios are very consistent and where they should be. Never pull knock except the normal -1.4 when my defrost is on. Pulls amazing and no over boosting. 5 stars no doubt.

    Installed on Legacy GT. Fits perfect other than the waste gate lip needs a little bending ( they told me this in the instructions) to allow valve to open all the way. A little trial and error, fit and bend.... and it went together nice. As far as the bolt up... perfect alignment. As far as the sound and performance, Amazing! but you knew that cause your friends car has one on it! Get it

    I went with this divorced waste gate DP cause I read it works well with the stock turbo. But at the same time a down pipe is a down pipe. The quality of this GrimSpeed downpipe is excellent! And I currently have it paired with the Invidia Q300. The power gains are what I expected with such mod and a stage 2 map from Cobb. I felt a more precise turbo spool and much better top end power. The sound this pair produces is a very deep rumbling tone and not extremely loud at higher RPM’s and very nice idle sound. Very satisfied! And very fast shipping from Rallysport Direct!
