Graves MotorSports for Yamaha MT-10 2022-2025 Cat Eliminator Exhaust System EXY-22MT10-CETC

Shopping with Bills has been an excellent experience

Shopping with Bills has been an excellent experience. They have been fully transparent about my expected delivery time.
Notifying me right away that my Arrow exhaust comes from a warehouse in Italy and I can expect a 2-3 week delivery time due to this.
There was a day delay from DHL to ship Bills the item and they even gave me that separate tracking number. Was shipped out promptly after Bills received it and UPS delivered a few days after.
I received updates on every movement and it was very much appreciated.
No other company I have shopped with has done this.

I highly recommend purchasing from Bills!

BILLS EXHAUSTS

It's beautiful, quiet, lovely sound.

It's beautiful, sleek, weighs half the stock muffler. And it has a wonderful much quieter sound than stock.
I love it!

Very fast shipping once again!! Very nice quality great sound

Very fast shipping once again!! Very nice quality great sound. A little louder at lower rpms than expected but does sound very good. Takes a little adjusting to get link pipe adjusted just rite to not leak at the bread box but it's nothing to complain about. I recommend purchasing the other carbon heat shield also it looks great! Thank you!!

I will be a life time customer

My journey will Bill's exhaust started back in January of this year when I ordered a Vandemon exhaust that has been on back order and I eventually learned there were no plans to make any exhaust for my BMW R18B anytime soon. I expressed my frustration with Bill's and they were always professional and answered my emails in a timely manner. I canceled that vandemon order and ended up ordering a Freedom Performance Exhaust. Despite my bad experience the first time around which wasn't Bill's fault, I went back and ordered because Samantha is absolutely amazing and her customer service is incredible and much appreciated. Samantha always replied back to me as soon as possible and I can't thank her enough for that because nothing is more frustrating than bad customer service. Big ups to Samantha she is definitely a real one and a great asset to the Bill's Exhaust team. Samantha deserves a raise and an all expense paid month long vacation.
