07 3500 t/d. Truck has now around 4k miles and I'm thinking on buying a BD tuner.
Question: is it too early considering the mileage ???
Also thinking on buying an exhaust.
Question: what size ? brand ? turboback ??
I had diesel before but never paid attention to their "high performance" just used them for work.
Any comments greatly appreciated. thanks.

2007 so im assuming a 5.9 only difference in exhaust is size, type of bends and material their made of. just dumping the factory muffler will help by lowering restriction, a 4" inch system will be big enough for most peoples mods. personally dont care for the sound of straight systems. go turbo back for best breathing and add a cai intake. lots of popular exhaust systems out there to choose from, if adding a muffler make sure its non restrictive

chip away but remember the tranny or clutchs life are questionable when adding extra hp with a heavy right foot
