Looks and Sounds Great!!

Very nice looking exhaust and sounds great. I had a cat delete with stock muffler. Bolted this on in a couple minutes and it sounds way deeper. Very satisfied, thanks!

Perfect fit and finish. Packaged well and shipped and delivered in a reasonable amount of time at the best price I could find online. Perfection all around! I was very surprised it sounded as nice as it did. And yet still not piss of my neighbors. Just enough to put a big smile on my face!

LEOVINCE LV-10 Slip-On Muffler - Full Black Z900 2017-2024 15204FB

It my 6th exhaust from Bill I keep coming back to Bill due to his exceptional customer service. You won’t find that in the big corporate motorcycle companies, Like Cycle Gear , Revzilla , any other corporate settings. When it comes to transparency Bill is the go to guy. His prices are fair and competitive. Highly recommend Bill Exhaust.

Love the look of the exhaust!!! Only complain is that you have to grind off the baffle. It was pretty easy and sounds amazing now 🦾

Sounds Perfect

Sounds Perfect ! Not too loud and not too low…and deeper at the same time…it is perfect for touring long distance. I went from Rio de Janeiro do Montevideo Uruguay, 2000 miles with this cool baffle. I strongly recommend. Ildemir from Rio de Janeiro Brazil

71600MI Arrow Racing Link Pipe for KTM 390 Duke 2013-2016

Good product, great service

The pipes that I ordered are typical Arrow quality. Getting rid of the CAT on the BMW 1300 GSA is the only way to make the bike sound good because the stock collector/ CAT has a huge built in muffler chamber around the CAT. You will need the exhaust valve eliminator but all of the O2 sensors are still functional. No tune, no check engine light, 1500 miles. All that aside, I ended up calling a few times to see about shipping and then to check status. Every time I called, Bill answered the phone. He was super helpful and a genuinely nice guy. You are buying a product form a fellow enthusiast and the customer service is exactly what you would hope for. Thanks, Bill.

The perfect finishing touch for my ZX4RR. Much lighter than stock and looks great! Can't go wrong with carbon fiber, sounds just as awesome.
Bill was great with communication also. I highly recommend.
