This MHC Plus G8X G80 M3 & G82 M4 Performance Style Rear Diffuser in Prepreg Carbon Fibre is the must have for your Quad exhaust set up. 

This product is made with the latest Pre Preg Carbon manufacturing processes to ensure the best possible quality and fit every time. This diffuser uses the original diffuser mounting positions. This diffuser will require you to modify your rear bumper to allow the exhaust tips come through the diffuser. 

Included in this diffuser is a carbon exhaust tip surround that clips into the diffuser 

This diffuser requires an M Performance or aftermarket exhaust that has centre quad exhausts. 


  • Crafted from prepreg carbon fibre with a 3k 2x2 weave (OEM Style)
  • Original mounting positions
  • Includes all diffuser parts to use with the M Performance or Aftermarket Quad exhaust
  • Coated in a high gloss lacquered finish


There are a variety of reasons why we recommend it to our customers. It’s far stronger than normal carbon, meaning increased durability and life span in the long term. Spend a little more now so you don’t have to come back later for replacements because you looked at your carbon the wrong way and hurt its feelings.

Pre Preg carbon is more consistent quality-wise when coming out of the mould, meaning less chance for issues or imperfections that would otherwise be undesirable in the finished product. The process eliminates air bubbles and results in a smooth, glossy surface more easily. This makes for the ideal part to compliment your car. If you are all about weight saving, Pre Preg is 70% lighter than alternative carbon options. It is the obvious choice when you’re concerned about performance.
