Description
xThe Akrapovic Evolution Line is a complete titanium exhaust system for the 2020-2023 Yamaha YZ450F and WR450F.
Evolution Line is the flagship of the Akrapovič range — the specification their factory MXGP teams run, built from titanium at the company's own foundry in Slovenia rather than fabricated from bought-in tube.
On a 450 motocrosser the exhaust hangs at the widest and highest point of the machine. Removing weight from there is felt every time the bike is thrown into a rut or picked up off the ground, which on a race weekend is a great many times.
The full system includes the header, which on a four-stroke shapes where in the rev range the power arrives. A slip-on leaves that half untouched.
- Complete system — titanium header, mid-pipe and muffler
- Evolution Line construction, Akrapovič's flagship specification
- Substantial weight reduction over the stock system
- Akrapovič part number S-Y4MET15-CIBNTA
Closed-course competition use only. Not EPA compliant and not legal on public roads. No spark arrester is fitted — one is required separately for USFS and BLM land.
Fits the 2020-2023 Yamaha YZ450F and WR450F. Yamaha redesigned the YZ450F for 2023-2024 and the later machines take a different system — check your model year before ordering.
