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

Sturdy Oil Filter Wrench
Color: Silver
I bought this sturdier Oil Filter Wrench when I was having trouble removing the oil filter on my 2003 BMW 1150RT with a stamped steel oil filter wrench that I had previously used. It still slipped, but adding a strip of grit mesh between the filter and the filter wrench saved the day. I still like this cast aluminum filter wrench better than the stamped steel one.

Does not fit Chevy LS3. Too big.
Color: Silver
Does not fit 2014-17 Chevrolet SS (LS3 V8) genuine GM oil filter. It slips. It's supposed to measure 74 mm flute to flute, but actually measured 77 mm with calipers. This wrench looks like it was used and was re-packaged with office tape. I purchased correct size from dealer that fits perfectly.
