Product Description

3" DPF and SCR Delete Kit for BMW X5D

Proudly made in Canada by BuzzKen 

  • Optional DOC cat greatly reduces pungent exhaust smell, highly recommended!
  • EGR blockoff plate included along with a top quality exhaust clamp
  • 1 simple cut is needed before muffler to install this and all hardware included for a bolt-in installation.

Are you building a race car or converting a car to off-road use only?

Start by replacing the restrictive factory DPF filter and exhaust with this mandrel bent downpipe and allowing the exhaust to flow freely! 

This downpipe is built to last with 409 grade stainless steel and a high quality flex pipe, it will also retain the 02 sensors and EGT sensors as the proper bungs have been provided.

Fitment Guide:

  • BMW X5D


  • Increases fuel mileage 
  • Improves exhaust flow
  • Lowers EGTs


  • ***Includes ALL required clamps***
  • 409 stainless steel from North America mills
  • 3″ OD 16 gauge tubing
  • Stainless steel installation hardware included
  • 100% bolt-on

  • Must be used with a tune, we recommend the JR Auto Performance tune for X5 35D, available here

 Also Recommended:


  • For Off-Road Use Only, this is not street legal and you will not pass emissions testing.

More Info:

-Our cats are made specifically to our specs by Catco in the USA. The same lifetime can be expected as from the OE cat, assuming the vehicle is in proper running condition. 'Plugging' should not be an issue, assuming there are no engine issues.

The flat clamp will be installed at the end of the exhaust, connecting the new exhaust to the stock muffler system.  The pipe for the stock muffler system should be cut right below the heat shielding where one heat shield overlaps the other.
