Got an Arrow exhaust system for my 04 Brutale S, also got the MV Corse slip-ons. Is this a bolt on system? Or should I get the headers/collectors/midpipe welded? Or can I just bolt it on, slipping the pipes together? I've got to get it tuned with the new chip at the dealer, and the nearest dealer is over an hour away from me. I inquired about the ballpark figures about getting it installed and haven't heard back from them. So, needless to say, I'm getting anxious to ride and I'm wanting to put it on myself.
