Great overall!

Looks amazing, obvious weight benefit, great sound but loud.
Installation is relatively easy but instructions could be improved

Best looking exhaust out right now. The picture posted isn’t quite correct. It’s a lot smaller way better looking. Exactly what I was looking for. It sounds amazing. It sounds contemporary and mean!

Bill’s delivered. Build quality is outstanding, fit and finish is perfect. No problem at all installing. Sound is louder than oem but not too much to upset the neighbors. Well worth the Arrow build time wait. Thank you.

Easy install except the springs. Buy a 10” spring puller. Sounds great. Nice welds. Typical Akrapovic quality and Bill’ Exhaust was best price and quick shipment.

Sounds amazing and looks really good

You guys saved my butt with this, I couldn't get it in my area since one of the shops were having tariff issues and not ordering arrow at the moment. But you guys did everything plus more of ordering it checking it and shipping it off to me. I didn't want to go with any other exhaust and you guys delivered. I will forever appreciate you guys and recommend you in the future.

M4 Exhaust Carbon Fiber Slip-On 2017-2025 2026 Z900 KA9004

⭐️⭐️⭐️⭐️⭐️ Premium quality and perfect fit for the S1000RR

Installed on my 2025 BMW S1000RR and the fitment was absolutely perfect.

The titanium finish, weld quality, and overall construction are excellent. Sound is deeper, cleaner, and slightly louder than stock without being excessive.

After the first ride, the titanium started developing the beautiful blue heat coloration that Akrapovic is known for, which gives the exhaust an even more premium appearance.

I had previously tested an aftermarket replica, and while it was surprisingly good, the genuine Akrapovic stands out in overall refinement, finish quality, and how the titanium ages with heat cycles.

If you’re looking for an OEM-quality upgrade that complements the BMW perfectly, this exhaust is worth it.

Bill’s Exhausts also had the best price I could find, with fast shipping, no tax charged to Texas, and free shipping, making the purchase experience even better.

Highly recommended.
