Dual exhaust anyone?
 

I am getting ready to do a simulated dual exhaust on my 02 7.3 PSD. I am probably going to Y pipe it just past the rear axle and I haven't decided if I am going to stick with the 4" all the way out the back or not. Anyone done this? Found a good place to get 45 degree angles and y-pipes?

Done it before but not on a truck your size.
