PHENOMENAL !!

Thrilled to finally have found a fair price for a race exhaust. Super grateful for the good deal. The Vandemon exhaust system is unreal ! The sound is phenomenal and I noticed instant power gain.

IN STOCK 71207CP Arrow Competition Evo Full Titanium Exhaust for BMW S1000RR 2020-2025 / M1000RR 2020-2024

Will Be Back!

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!

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.
