Dinan Valved Axle-Back Exhaust - 2021-2025 BMW M3/M4

The G8x M3/M4 is arguably superior in every category to its predecessor but in most, if not all, circles the biggest downfall of the platform is in the sound department. Like the F8x before it with the S55, the S58 in the current generation leaves a lot to be desired. While a step in the right direction from its forerunner the stock vocals still carry far too much rasp that do not fully articulate the refined aggressiveness typical of the brands signature performance models. Dinan corrects this weakness with a valved axle back exhaust system that elevates the tone to a deeper, more meaningful note while also delivering an extra level of amplification above and beyond its stock counterpart. Coupled with the optional middle exhaust / x-pipe for the platform an even louder, smoother, and fuller soundtrack is possible.

Features:

  • Maximum gains of +6 HP and +5 lb-ft of torque
  • Enjoyably louder, sportier sound
  • Drone abatement technologies used to reduce cabin resonance
  • Four, diffuser filling, 4.5-inch (114mm) double-walled, polished stainless steel clamp-on tips with laser engraved Dinan logo
  • Larger diameter piping for increased flow (76mm vs. 70mm)
  • 6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds)
  • Stock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings
  • Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions
  • 100% 304 Stainless Steel construction
  • Factory-like fitment with included mounting hardware

The Thick Red and Black Spaghetti of Power
Size: 20FT Black & 20FT Red
If electricity had highways, this would be an interstate. The cable feels substantial, the copper conductors are flexible enough to work with, and the included lugs and heat shrink tubing make installation easier. Great for batteries, inverters, solar systems, RV electrical upgrades, marine projects, and welding setups. Voltage drop stays low thanks to the heavy gauge construction, and the insulation feels durable enough for demanding environments. Overall, a solid wiring kit that inspires confidence when moving serious current.

Great cable kit.
Size: 20FT Black & 20FT Red, Size: 20FT Black & 20FT Red
Great heavy duty cable. Good thick feeling insulation that looks the real deal. Wire is soft enough to route easily without too much resistance. Appreciate it coming with the lugs and heat shrink instead of you having to source extras. Seems to be truly copper as listed. Great deal for the length if so. Worked for what I needed on my UTV.

Cheap price for the cable and terminal ends with heat shrink.
Size: 20FT Black & 20FT Red
Good 6 gauge wire, jacket seems sturdy and like it won't crack easily over time like some wire. Comes with all the connectors shown too so you don't need to find end ring connections to terminate the ends. Just need a punch or crimp tool for the terminals but if you already have that then just cut your wire length and add the ends for battery cable.
