Well, they don't have to be tacked onto the invoice, but it would be nice if they were included in the package. Treating it separately would be fine for those who want them. I just figured that shipping a bulk of them to a single address would be a lot cheaper than shipping individually to multiple addresses. WakenSS' idea could work for me as well.

Any way we can get the crush gaskets tacked onto the invoice?

Hmmm, I wonder if anything else can be done to get some more power? Maybe adding h pipes between the primaries, or an h pipe after the 4-2 merge, or maybe a lextek design with tbr diameters? The latter would be a challenge without having one though.

That's still an amazing price for some dyno runs and a tune. Geez. IIRC, the shop local to me charges $400 to tune including a power commander. When I dynoed my 98' a couple years back, it was making 106.5whp with just a k&n big filter, slip on, and ngk iridium ix plugs. I think it had around 3k miles then, so the dyno test bike is running like new 👍

In for 5th gen full system. What's the muffler gonna be? I like the sound of my Delkevic 8" slip-on, so I'd like something similar with minimal baffling.
