OVERVIEW    

Looking to elevate the external acoustics of your G8x but want to upgrade in stages and/or not break the bank? The Dinan Middle Exhaust for the G80 M3 is and G82/G83 M4 introduces a more aggressive tone and an increase in volume over the stock system while retaining the factory muffler at a budget friendly price point. Should the desire for more arise however, it can easily be paired with the matching Dinan axle back exhaust for further aural enhancement and a more aggressive growl. It is a union that boasts a bold, yet sophisticated, exhaust note that neither can fully achieve on their own. This middle exhaust itself removes the hydro-formed factory center section from the secondary catalysts back to the axle back, including both resonators, and replaces it with larger 3-inch T304 stainless steel tubing for freer flowing capabilities. In place of the forward factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes which are commonplace in the market. This hand-made 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is present in the stock system. Along with the inherent benefit of increased volume by removal of the resonators, the Dinan X-Pipe for the G8x M3/M4 produces a louder, smoother, and fuller exhaust note that will deliver smiles time and time again.

Features:

  • Smoother, louder and sportier sound
  • 76mm (3-inch) tubing replaces stock 70mm (2.75-inch) tubing for free flow
  • Deletes resonators between the secondary catalysts and rear muffler for increased volume
  • Includes X-pipe crossover made from mandrel bent tubing for minimum restriction
  • 5-pounds lighter than the stock mid-section (Stock: 22-pounds vs. Dinan: 17-pounds)
  • 100% 304 stainless steel construction
  • Factory-like fitment with included mounting hardware

good experience so far
Size: 60 Count (Pack of 1)
I’ve been taking Qunol Brain Health for a little while now, and overall I’ve had a good experience with it. What stood out to me first was that it didn’t upset my stomach, which I’ve run into with other supplements. I feel like I’ve noticed a difference in my ability to stay focused during the day, especially when I’m working on tasks that usually make my mind wander. My energy levels also feel a bit steadier, without that late afternoon mental fog. The capsules are easy to swallow, and I like that it combines several ingredients aimed at supporting memory and concentration rather than having to take them separately. It’s obviously not an overnight miracle, but with consistent use I do feel sharper and more mentally “on.” The only downside for me is the price—it’s a little higher than some other brain supplements I’ve tried. But considering the quality and how it makes me feel, I think it’s worth it.

Definitely worth it!!
Size: 60 Count (Pack of 1)
After completing one bottle, I have to say that I have noticed a difference in not just my short term memory, but overall, how I can focus throughout the day. I'm on my second bottle now.

Memory Health
Size: 90 Count (Pack of 1)
I began Qunol Brain Health Memory Plus this year and am very pleased. I feel my memory is much better, although not perfect, I have more confidence while taking the product.
