Hi all i have a friend who has a 2005 blade and he has just fitted a beowolf exhaust and wants to get it on a dyno. I dont know anything about the rr-5 models, Do they have a o2 sensor like the 08+ models ? Sorry for the dumbass questions but im going to fit a pcv for him next week and wanted to do everything in 1 go any feed back from people who have a beowolf can on a rr4/rr5 would be brilliant
