I have an 03 gsxr 750 with an M4 bolt on stainless steel muffler with the carbon fiber tip and OMG I have to pull over and wipe after blipping that throttle a few times..Sounds absolutely gorgeous..Those of you that have gixxers with M4's installed already know this....man!😎😎🤣🤣😆
I wonder if the 2022 model headers and cat are the same as this 2020 model, or if there have been more restrictions added to meet EPA standards. I'm going to get a 2022 or 2023 model and want to go with just the M4 slip-on, hoping it sounds the same as your 2020 model.
