Going to put ebay SE slipons on my '03 FLSTCI. Already have a Ness Big Sucker and a Techlusion dfo, so I suppose I'm close to being Stage One.

I'm gonna use SE exhaust gaskets. Is that something I might be able to actually feel....is flow significantly improved, or is it pretty minimal?

the gasket dosnt squish into the port,like a stock one might

Right, but what are the real world effects of squish/no squish?

anybody with a flow bench and extra time on there hands out there?
im sure harley has spent thousands of dollars in r and d on this.
if it made a big difference i think they would state it i.e. 10% more flow.
if they told you the truth...you wouldent buy them

i would think it is minimal. I put them on my 03 FLSTCI when I put slip ons on my ride. but really what would be to be expected out of just a different exhaust gasket.

I think I saw something somewhere that said they were good for 7-10cfm, but I really don't know what that means in the real world.

I just replaced my stock ones with another set of stock ones and if you are careful I don't see how they would block any flow. The original ones were a perfect fit in the exhaust port ie none of the gasket material was impeding any flow.
