Default Single 3.5". What do I need?

I've already had this setup but sold it. Besides the point, I forgot how many bends I used. I bought the TSP SS headers then going to do dual 3" then Y it into a single 3.5". How many bends and straight pipe of the 3" and 3.5 do I need?

I think I made my 3.5" out of 4-5 45* bends and no straight pieces other than the flow master merge that's straight for about 8-10" after the y. Mine was dumped before the rear axle though so if you're wanting to run an over the axle pipe you'll obviously need more than that. Haha

I used 2 90s and 1 45 on the ypipe. Into a 3.0 to 3.5 ypipe. Then i used a long straight piece of 3.5, probably 3 feet. Then i used 4 90s togo up snd over the axle. Then a 3.5 to 2.5 ypipe branching into each corner.

You'll save more weight putting your truck's engine in a rx7 or mustang.

What I'm saying is, it's a 5000+ pound truck...

Buy the 3.5" over the axle section from summit(mangaflow brand) $60, free shipping, then all youll need is a couple of feet of straight 3.5" pipe from the Y-back.
