Question

i already bought 3" series 40 flowmaster muffler
is there a 3" pipe kit from header to muffler
that I CAN BUY.  

Answer
Tim-

  I don't know of any kits specific for that application, but even if there was one I would still advise against it.  It would most likely be cheaper to just go to a local muffler shop that's had some experience with custom exhausts and have them bend and weld up the piping themselves.  This kind of work isn't rocket science so there aren't a lot of muffler shop mechanics who won't take on the job.  This is what I've always done and I've had great luck doing it.  Hope this helps.
