Shawn's back to tell you everything you've ever wanted to know about stepped headers. www.rinehartracing.com #americanpipesforamericanbikes #rinehartracing.com
We really don't recommend any sort of inserts or anything like that. In theory, they might provide some additional backpressure but in practice, they never seem to make any difference and they are prone to breaking or cracking, leading to rattling in the mufflers.
The Y pipe does a good job of exhaust scavenging, but it doesn’t equalize the backpressure as well as the H pipe, which is much more important on M8’s.
I wish he hadn’t said “everything i ever wanted want to know”. I wanted to know so much about these thingys and yet this video is two minutes long and basically just a definition of this concept generally. smh!!

Thank you for answering this question that has been bugging me forever. Do you have any opinions on properly designed lollipops for non stepped pipes?

Will it make a diffrent sound in a single cylinder bike too?
We design all of our headers for V-Twin, so we can't necessarily say if it would or not.
Which is better, H-pipe or a Y-pipe?
The Y pipe does a good job of exhaust scavenging, but it doesn’t equalize the backpressure as well as the H pipe, which is much more important on M8’s.
How “big” are the steps? Are they around 1/8” bigger?
We can't give ALL the info away ;)
Yes.

Alright! What do you want to know?
