I have vanemon exhaust on my 25 rocket gt. One sensor. I do not have tune. The bike works flawless and no lights. Feels like more snap in throttle and pulls hard. I did not go for the header as I think that may require a tune. I will be looking at the BT ECU Tune.
I ordered werkes for my 25 storm. They emailed me back and said it was not compatible, only up to 2024. Refunded my money and cancelled my order. So now I’m lost if you got it. ???
