How hard is it to do this?
tired of the hose clamps coming loose, or the rubber, or just the looks of it.

thinking about going with stainless marines manifolds and stainless elbows.
want to complete the 'look' with piping.
is it possible?
is it possible to keep the y pipe?
or do I need to go straight out?

I built some out of 4" sched. 10 pipe.Heavy but avail.Inside dia. is about 4 1/8" fits over the riser and uses set screws so no clamps,just silicone on the inside.Polished it all useing REV Marine cast Alum risers. We''l see if it holds together,if not I'll split the pipe on the bottom,add a bolt over the split to tighten and silicone again. Kinda hookie,looks great,just gotta make sure my transom stays dry and exhuast water doesn't seep into the wood. Also using a piece of rubber on the opposite side of the the set screw to hold the opp side. You'd have to weld a piece on the bottom for silent choice,I took mine off.

If your changing to stainless marine manifolds or any similar type buy them with the long risers.
