4" or 5" exhaust
I have a stock 2000 PSD and am looking to install the wicked wheel in the near future. After that it will be an AIS and Exhaust. And eventually a chip (DP-Tuner) or programmer(not sure, Edge maybe?).
I plan on installing the exhaust from the turbo back, should I install a 4" or 5" exhaust? Are there major horsepower, backpressure issues with a 5" over a 4"? I dont think I want stainless if this makes a difference.

From what I have read there is no difference on our trucks between the 4" or the 5" exhaust.
The big difference is how much better the 5" sounds.

I notice that the downpipe on your system is a 4", are most of the 5" systems this way?
