Excellent Product

I was looking for this exhaust for a long time and finally found it at bills exhaust. The exhaust sounds good! Bills exhaust did a great job from the time I ordered it until I received. Highly recommended.

Excellent product

I needed to upgrade my stock fender and didn’t want to cut wires and this product was easy to install and you use the factory license plate light without cutting wires. The installation was very easy to me. The customer service is great and also the shipping was very fast which I was impressed and definitely ordering all my parts from Bills Exhaust.

Vandemon 4-2-4 system for z900rs

Great system. Unfortunately there are no instructions whatsoever. I assumed that a clip went between the left passenger foot bracket and ended up breaking a $100 foot bracket on my motorcycle. Couldn’t believe it!!! How hard would have it been to just put a simple drawing in with the exhaust system to at least picture how it needed to be assembled. Hopefully JB Weld will glue this back together. :-(
On a brighter note, BILL’S EXHAUST STORE is absolutely awesome!!! Super customer service and Bill was really nice and kept me updated on my order the entire time. Highly recommend!!! Thank you Bill !

Great service and product exactly what I ordered

Bill was awesome. He helped me be certain the part I was ordering was what I wanted. Kept me up to date on everything. Seriously, a great choice on my end. Hopefully I don’t need to replace another muffler, but if I do, I’m coming back.

Perfect Fit for my 2023 Streetfighter V2

A huge thanks to Bill, for keeping the communication going while the part was on its way. Bill took the time to understand what I was looking for and guided me with the purchase. I am happy with the Arrow Slip-on Exhaust. The bike sounds so much better and I can feel the performance change, also the throttle is a lot more responsive. This is an Exact Fit from Panigale V2 to Streetfighter V2. Thanks Bill.

My Gen 3 Busa is now a real Jekyll & Hyde with this kit

Once again Service from Bills was spot on. Wanted a lazy point of difference on my gen 3 Busa. local supplier said 4-6 months wait in Aus it had to arrive all the way from US. Pffft, I contacted Bills and shazam it's here within 14 days. Out on the country roads, factory QS is fine but in start stop traffic around town my left ankle from a past injury reminds me of why I shouldn't be on a Busa or a sports bike. This kit integrates perfectly and seamlessly. you get the cake and eat it too. All stock QS and manual clutch operations work as per normal but add another element to my bike. I actually prefer turning QS off in Busa menu and run solely the Pingel. Affectively Its paddle shift for your bike. The supplied electronics does what it supposed to and from my experience the best settings for general and spirited riding are 80ms on the kill module. It's a luxury, sure. But one that takes my riding and cruising to another level. as stated no more than 3 hours to fit. People look at me weirdly sometimes, thinking WTF?? and often slow down. Works as it should, and Bills service as always was top notch. Thank you mate very happy once again. Keep up the great work and see on the next purchase.
