Where can i find a good 5" down pipe for my truck?

Thanks

I have one coming this week from diamond eye. Its 5 inches all the way from the turbo to the muffler. I am going to buy a 5 to 4 coupler and see how that does. The pipe cost around $100.

 

my shopdiesel 5" exhaust came with one

I got my Diamond Eye 5" turbo back system last week, whole thing cost $450 w/ muffler, clamps, etc. Seems well made. Haven't put it on yet, probably put a Donaldson muffler instead of the straight thru one for the noise level.
