If you're tight for cash just loose the muffler. If you decide to do the whole system make sure you go to a place that will actually use a proper pipe bender and not the "heat up the pipe with a torch and bend it like corrugations" method. It seems that here in Central America most muffler places do NOT bend the pipe properly. If you cannot find a good muffler shop DON'T change the piping. The corrugations will offset the size gains. I have 2 1/2" pipe on both the BJ60 and the 3B turbo powered FJ55. The FJ45LV will also get 2 1/2" pipe. None of them have mufflers and we have NEVER been asked about it either even at AirCare!

I STRONGLY recommend AGAINST any fuelling adjustments unless you have a pyrometer installed. Maybe someone can send you one where ever you'll be for a few weeks. I have not changed the fuelling on my BJ60 when I installed the turbo and I CAN get it too hot. The FJ55 supposedly has the factory adjustments on the fuel delivery and I can EASILY get it WAY too hot!
