Without a doubt, the best of the best, it's wonderful, it sounds incredible and the service is excellent.
I recently purchased the Arrow Race-Tech Slip-On Exhaust (Aluminum Dark) for my Kawasaki Z900 (’17–’24), and I couldn’t be happier. The quality is top-tier—lightweight, beautifully finished, and it gives the bike the deep, aggressive sound it should’ve had from the factory. Throttle response feels smoother, and the overall riding experience is noticeably more exciting.
Huge shoutout to Bill from Bills Exhaust. His communication was excellent from start to finish—quick replies, honest info, and genuinely great customer service. The exhaust shipped fast with no delays, no issues, and no backorder nonsense. Exactly what you want when ordering parts for your bike.
If you’re on the fence, go for it. The exhaust is incredible, and Bill makes the whole process even better. Highly recommend!
Arrived super quick, no complaints
Great customer support, fast shipping and delivery , and great quality exhaust . Sounds nice 👍🏼 would definitely recommend
Fast service and the pipe is very well made.
Purchased the power core 4 along with the mega bomb header. Sounds great! Looks even better! Slammed them both on my 22’ KX 250f.
Was trying to find a reseller for Graves products. Stumbled upon this site. No hassles. Ships to Australia (big plus). Now I can mod my dream bike.
Exhaust is gnarly, obnoxious... exactly what I want! Makes all the right sounds.
I'd buy another one if I had another bike.
Super easy fitment, shaved off so much weight with the titanium build.
Absolute piece of art.
Great price and amazing sound.
This system with a BT Moto tune sounds and feels amazing. The weight reduction, power increase makes this bike handle even better.
The titanium exhaust system looks amazing.
Excellent
Perfect fit.
Came in just 4 week to Canada couldn’t be more happy with the overall sound and fit the pipe cleans the bike up so much
Amazing piece, pro shade lens is a game changer. Looks super sharp too. Beautiful!
Box arrived damaged from UPS but because of the great packaging it was un-damaged. Fit perfectly on the bike.
Love it, love the sound, way lighter than stock exhaust.
