Well what Farkles are you going to put on it first
Lamonster cat delete pipe then Spiderpop lights
Why the cat pipe?
I've always removed the cat from any bike I've owned to cut the heat plus the cat weighs 30 lbs. But I was getting an average of 45-48 mpg with the cat now I get 35-40 mpg.
you changed the back pressure that the ecm was looking at to do its calculations. look at DK products. they sell aa disk that can be installed to restore some back pressure putting it back in tune without the cat issues.
