The Active Autowerke Valved Rear Axle-Back Exhaust is designed specifically for the BMW X3M and X4M (F97/F98). It addresses the stock exhaust's subdued sound by providing a deeper, more aggressive tone while retaining stock valve functionality.

  • Made in the USA from 304 stainless steel
  • Engineered to increase sound level and optimize exhaust flow
  • Utilizes factory valve actuators for controlled exhaust tone
  • Test-fit on F97/F98 exhaust fixtures for guaranteed fitment
  • Complete with all necessary installation hardware
  • Fits all F97/F98 BMW X3M and X4M models

This axle-back exhaust pairs best with Active Autowerke mid-pipe and catted downpipes for a full system upgrade, delivering an authentic M-car exhaust note. Replacing only the rear section provides a subtle sound improvement, with the most dramatic enhancement achieved by also upgrading the mid-pipe.

Great Watch for a Great Price
Color: Dark Brown band & Rose Gold bezel & Navy Blue dial
⌚ “Simple, clean, and gets compliments every time.” ⌚ This Watch has easily become my go-to watch. What I like most is how clean the design is. It’s not flashy, but it stands out in a classy way. I usually pair it with brown shoes and a belt, and it pulls the whole look together perfectly. Another big plus—it doesn’t feel heavy on the wrist. You can wear it all day and forget it’s even there, which is exactly what you want in a daily watch. And the compliments? They come consistently. It’s one of those pieces people notice without you trying too hard. ✔️ Clean, stylish design ✔️ Lightweight and comfortable ✔️ Pairs perfectly with dress or casual outfits ✔️ Gets a lot of compliments If you’re looking for an affordable watch that looks sharp and feels great, this is a solid choice.

Unusable Adjustment Diagram – Completely Black
Color: Mesh Strap watch silver balck
The watch itself looks nice, but there is an issue with the instructions for adjusting the band. The included diagram is completely black and does not show how to make the adjustment. I was only able to adjust the band because I had a diagram from a previous watch. Without that, it would have been very difficult. The manufacturer should provide clear and readable instructions.

You won’t be disappointed with this one
Color: All Golden face Big Dial
Looks great fits great I was skeptical about getting it because I purchased another variation and was not happy at all but I like the way that this one looks so I said I’d give it another shot. I’m glad I did. I’m very impressed with it.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.
