Genuine Exhaust import from UK

"Why Inconel?"

Unlike Titanium it will not burn through, it can be as thin as 0.37mm wall due to it's unrivaled strength.

By holding high temperatures this keeps the ambient temperature low, it also cools down very quickly.

Take a look :)

    After quite possibly the longest 42 day wait of my life my complete m4 exhaust was finally in my possession. Worth the wait and I’d order from bills again.

    ⭐️⭐️⭐️⭐️⭐️ 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.

    Quick and easy install no modifications required.

    These pipes are great! Very light compared to oem, around 30 minute install, andall parts fit perfectly. I also installed an arrow muffler, sounds great! Noticeable power improvement even without tuning.

    Sounds incredible

    Bill’s Exhaust was super efficient with shipping. The exhaust sounds loud and incredible, much better than any videos I’ve seen on it. Install was easy enough. My bike’s a 2025 Honda Rebel 1100T and I needed to reuse the original gasket. To me, it looks amazing. Love it!

    Awesome Upgrade!

    The LV-10 was just what I was looking for in a slip-on. Minimalist design, easy installation, and added just the amount of growl to the exhaust without being obnoxious. It also keeps me inside some of the crazy exhaust and noise laws in New York. Bills Exhaust had the unit shipped to me in a few days. Installed onto a 2025 Monster 937+

    New 2026 Indian 101 Scout comes loaded but the factory exhaust is a sleeper

    New 2026 Indian 101 Scout comes loaded but the factory exhaust is a sleeper. Well, the V&H HO woke that bugger up! Shifting far smoother, revs up faster and it now sounds like 1250engine. Took minutes to install. Mahalo to Bill's for USPS shipping to Hawaii ($20 instead of $200), much ALOHA being sent your way.

    Digging the Arrows

    First time trying Arrow Exhaust. I was an Akrapovic fan boy. I’m happy with their quality and sound. Fitment is perfect. They don’t come with a bracket for the side panels but it looks fine without them (HyperMotard 950). They sound great. Classic deep tone without that bubbly idle noise more open exhausts have. Proper bark up high. A bit louder than the stock cans at all revs but never annoying and very quiet with neutral throttle. There’s a little decel popping with the stock map and valve disabled. They look great. First time shopper at Bill’s and everything went as expected. Shipping time and delivery was right when they said it would be. Good communication and packaging. Awesome all around.
