Ok, I'm 16 years old and bought a 95 gmc 6.5 liter turbo diesel. I want a bigger exhaust on it but idk how to get a down pipe to go from my 2" turbo to a 3" or 4" exhaust pipe. Where do I find the down pipe or an adapter?

 

Flowmaster makes a set that includes the down pipe and a crossover pipe. I would then get the diamond eye 4inch turbo back will be around 450 for everything

 

x2 on that. Im running a different cross over that suggested but either way the diamond eye exhaust system is the way to go.
