1973 & Up Exhaust Options Wanted

[mtchevytruck]

Need any exhaust experts to weigh in on choices for box body exhaust. Searched the site and found a few ideas but mostly for the earlier trucks. I have headman headers on a lowered swb 1977 c10 with flow masters, and a mild built 350 (325ish hp). I need to replace the pipe and am trying to decide where in the system the mufflers should be. Weather they should be toward the front of the truck or closer to the exits, or if makes a difference at all? Also weather I should have a cross pipe installed between the two? And lastly and most importantly, where to exit the tips. Leaning toward running them out at an angle in front of the rear wheels (love the stereo side pipe sound). May consider dumping them after the axle at a slight angle. Also saw a neat but very expensive thread on using boat/marine tips through the bed side (can't afford) Pictures of exit ideas would be appreciated.
