Love it and it Style Seamless integration

Very easy to install my only complaint is I wish you would include O2 sensor bolts to cap them off but this was fairly easy fix with 2 Dorman 12m x 1.5 and 2 thick copper washers, I even had the ECU tuned by Vcyclenuts since I have a US 2024 ZX4RR 40th Anniversary Edition model which has been neutered, Absolutely love the sound of the auto blipper I can actually hear it unlike before I could only feel it And she totally sounds amazing
