Does anyone know what is the difference between the rev up art pipes and non rev up ones?
I bought a new set but they told me they arent going to fit? (muffler shop)
Saying that it has 1 extra bolt hole?
Please start new threads in the appropriate sub-forum, it is a rule after all to do so. Also, if you had taken the time to search for your answer instead of asking something that's been discussed tons of times (hmmm that's a forum rule as well) you would have had your answer by a little after 3 PM this afternoon.
Or you could have just sent Tony with Motordyne a PM and gotten your answer from the man himself. So many options...............................
