The Fabspeed BMW M3 & M4 Valvetronic Exhaust System offers a superb “plug and play” upgrade to the restrictive and quiet OEM exhaust. Adding a significant increase in tone, volume, and power. We use Helical valves imported directly from the U.K. to eliminate any risk of valve failure that plague many other options on the market with low quality exhaust valves.

SOUND:

The Fabspeed Motorsport Valvetronic Exhaust System relieves you of the subtle OEM sound and gives you the volume and tone that’s missing from the factory system. With a slight increase in volume on the throttle and a nice burble at idle, this is the perfect “grand touring” M3/M4 exhaust system. Downshift pops and bangs in sport mode are louder, but not obnoxiously so. This system has no drone at all cruising around town or on the highway.

FEATURES:

  • Fits all BMW M3 & M4 (G80/G82) sedan/coupe vehicles including Competition Models worldwide (2021+) (RWD & AWD)
  • Constructed from CNC mandrel-bent 14-16 gauge T304L stainless steel 
  • Laser scanned and CAD designed for perfect OEM fitment using Ametek Handyscan 700
  • This cat-back system is emissions legal in all 50 states and the rest of the world (ROW)
  • Uses aerospace quality Helical Limited exhaust valves imported from the U.K.
  • No CEL (Check Engine Light) guaranteed
  • Saves 3lbs / 1.4KGs compared to the factory system
  • Includes Deluxe Quad-Style Tips in your choice of finish
  • Retains factory valve functionality for “plug and play” installation

Does what it says
Size: 16 Fl Oz (Pack of 1), Style: Individual
Have a JD 280 and it was not running well at all. Surging, not running good overall, where as previously it was. I used this and after a few hours of running, it cleared up very well and runs like a "Deere" now. Product line is still, one of the best out there. Bought again for my chain saw and use it in my weed wacker too.
