"H" or "X" Pipe advice Please

My "H" pipe setup from tti

Full 2-1/2" from manifolds to rear


This is a correct exhaust as they were . Very Nice. This is excactly what I want on my duster I am building. But no clamps I use tabs. Male and female that weld on four on each joint. Then two short 1/4 20 bolts. The exhaust can be removed or put back on without any use of a hammer or any force. Take out the two bolts and slide it apart. The only clamps used are for the rear hangers .

Who sells factory 1970 exhaust 2 1/2 front pipes and 2 1/4 tail pipes with the correct bends? Including the bends that turn the tips up as they are suppose to so the drain holes work.
