Linky?
This one?

It doesn't have the length a Long Primary TH has, it's that length I attribute to the low RPM torque.
The Bassani looks like it would be better than a Pro Pipe.
Not enough better to warrant the expense if you already have a Pro Pipe.

I've never been impressed with short pipes

The ideal combustion chamber size depends on the compression you want to match the cam you're going to run. If you're trying to increase compression by just milling the heads you'll have to take a lot more off than if you went with pistons that are designed to increase compression.
I do business with a shop in Western Australia. Maybe they can help you.

That was an original shovelhead 2:1 pipe that had the fat sausage (low restriction) muffler.
Someone had beat up the muffler and there were some scuffs on it so it wasn't good for a resto.
I had to rework it to fit the trike frame and the tall motor.
I put a megaphone on it with a steep reversed cone at the outlet to tone it down.


This is the one I favor over a ProPipe

I found a thunder header (I think) in the post above which actually looks pretty good.
