New exhayst
I’m planning to buy a Dominator full exhaust system for my brand new 2026 MT-07. However, I have a couple of concerns regarding the engine and the factory warranty, and I could really use some advice.
My main goal is to avoid damaging the engine, but at the same time, I absolutely do not want to void my warranty by flashing/tuning the ECU.
My question is: Can I get away with just buying and installing a plug-and-play Lambda/O2 sensor optimizer (like a BoosterPlug or similar)? Will this be enough to keep the air-fuel ratio safe so the engine doesn't run too lean with the new exhaust, or is a proper ECU tune/flash strictly mandatory for this bike?
I know a full tune voids the warranty instantly if the dealer checks the ECU, which is why I’m looking into the optimizer route as a temporary/removable solution.
Has anyone done this on the newer Euro 5+ models? Any feedback on engine reliability and warranty issues would be greatly appreciated!
Thanks in advance!
