Want to build a set of shot gun stacks but wasn't sure if I could buy a 5" y pipe or if I would have to fab one. I can do all the fab work myself but wanted to see if anyone has done this before that could give me some pointers.
I ran these's for a little while.. just a custom chamber at the bottom with 1 5in inlet. It wasn't bad, only got rid of them because it douched that light right above them. :bang
I did a dual bull hauler set, it looked pretty good, I just made a "box" for them out of 1/8th" plate, too much heat from welding, warped it, so it leaked a little, bit not too bad. I'll find a pic and post it up.
My 02 duramax has a utility body. It has a 3.5" downpipe to 5" pipe, through a high flow muffler into a short dual 4" splitter, each dump into a 7"x24" pipe. The muffler originally took the crack sound out of the exhaust, the tip puts the crack back in it! LOL
In my opinion anything other than straight cut pipes mounted horizontal and side by side is not the shot gun look! If mount like stacks they are simply dual stacks. Then again, shotguns are seldom chrome!
