3" Monster Downpipes for the GLC 43. These downpipes will only come to market Late Februrary or March 2022 so save your pennies.

  • These will be the same spec as our C43 monster series pipe and you will get no check engine light with our appropriate and recommended spacers

  • Guaranteed no rasp or nasty sounds, your truck will stilll sound like a truck

  • 98% the flow of catless, so why compromise on noise or smell.


  • Redesigned with 3" piping and a larger body

  • Deeper throaty sound with 15% more flow than our standard pipes

  • Entire Down Pipe is constructed out of rust resistant T304 SS for durability

  • Original Stock Downpipe is 3D scanned and reverse engineered for perfect direct bolt on fitment

  • Thick 8.5mm welds to prevent leaks or cracking

  • Argon gas back purged welds for penetration and seal =Long life

  • CNC T304 flanges, with connection directly to the Turbo outlet V-band

  • Get rid of that nasty smell that you get with catless downpipes and that awful "rasp" that come with de-cat pipes. Unleash a deeper, refined rumble: This is primarily due to the fact that engine pulse waves can expand in the barrel of the main catalyst body providing

  • Near identical performance to de-cat Downpipes, along with a throaty sound and without the smelly fumes.

  • turbo spools up quicker for better throttle response and unleashes up to 20 HP and 20 TQ

  • Quicker spool allows the power to come in earlier with being able to hold it longer

  • can allow you to go stage 2 on a tune to allow up to 30-40 more HP and Torque

  • re-map using JB4 data log and take advantage of the higher flow for that push you back into your seat thrust around 2500 rpm
