DescriptionThe whole story▼
The Arrow Competition full exhaust system 71231PTZ brings track-focused engineering to the Yamaha YZF-R7 without demanding a professional race team budget. Combining a stainless steel header with a titanium silencer and carbon end cap, it delivers a genuine reduction in unsprung mass alongside a more direct throttle response — making every session on circuit feel sharper and more rewarding.
Key Features
- Full system design replaces the entire stock exhaust from header to silencer for maximum weight saving and unrestricted flow.
- Stainless steel header offers excellent heat resistance and long-term durability under sustained high-rpm use.
- Titanium silencer body keeps overall system weight to a minimum, improving handling balance and acceleration.
- Carbon fibre end cap adds a premium finish while contributing to thermal management at the outlet.
- Removable dB killer included, giving you flexibility to adjust the sound level to suit individual circuit regulations.
- 250 mm silencer length with a 54 mm inlet and 43 mm outlet, engineered for optimised exhaust gas velocity on the CP2-engine R7.
Performance and Everyday Track Use
For riders who use the YZF-R7 as a regular track day weapon, the Arrow 71231PTZ represents a straightforward upgrade path. The complete header-back replacement ensures that every element of the exhaust path is optimised together — there are no compromises from mixing stock and aftermarket sections. The result is a more linear power delivery that suits both novice track day riders building confidence and experienced pilots chasing lap times.
Arrow recommends using a dedicated ECU mapping when fitting this system to ensure the fuel injection is correctly calibrated for the freer-flowing exhaust. Pairing the system with an appropriate map will unlock the full performance benefit and protect engine reliability.
Build Quality
Arrow's Competition range is built in Italy to exacting standards. The stainless steel header is precision-formed and TIG-welded for consistent wall thickness throughout. The titanium canister is polished to Arrow's characteristic finish, and the carbon end cap is finished with a clear lacquer to resist discolouration from exhaust heat. All hardware and mounting brackets are included for a direct, hassle-free installation on the R7's frame.
