I'm aware that going from stock/slipons to a full exhaust system that it's highly recommended to have a bike tuned to accommodate for the additional airflow being introduced. My question is if I already have a full exhaust system that's been dyno tuned and I change to another brand full exhaust system, is a new tune required/recommended?
I currently have a dual side full exhaust system on my ZX14R and want to switch over to a single side full exhaust system primarily for the sound characteristics and the weight savings. Bike runs great in its current form but I'll prefer not to plop down more $$$$ on another dyno tune if it's not necessary.
Thanks
