When I replaced my muffler and pipes I didn't need the stainless tip.
I went to a semi-truck parts place, they allowed me to pilfer through their large bins of 5-inch exhaust fittings. I had figured out what I needed to
replicate the original. My original was mostly welded together however
even though I have a wire welder I assembled it with slip-together joints.
That way I could adjust everything in place until I liked it. The wide band clamps really work well.
If you need the stainless chrome tip you may find something here
