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.

Arrow Yamaha XT1200Z Super Tenere Exhaust Collector Pipes for ARROW slip-on stainless steel 72095PD

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!

LEOVINCE LV Pro Muffler 14344E

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.
