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 👍

Or sfdownhill can just hyperlink all updates on the first post.

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.

Nah, it's all good. My thought process was simple: Does the Lextek also have the indention on the rear downpipe? Nothing more than that. Two generally equal systems should perform generally equally to each other. Bashing headers to fit V8s in some cars doesn't do anything to horsepower, so one small cave-in on one pipe shouldn't do much as well. Looking at the pics, the primary indicator the BW is a BW is the indention, but since the pipes are turned around the other side in the Lextek pictures, I was wondering if there was a chance the Lextek had it as well. Regardless, they're of the same design, so performance is going to be within margin of craftsmanship anyway. The Lextek is cheaper, comes with a mid-pipe, soon to come dyno results, and a seller is willing to hook us up on a group buy, so I'm just waiting to see how this unfolds.

No, I'm just asking a question. Calm down.

Does the Lextek also have the indention on the rear downpipe?

Oh yeah...duh. I forgot it was on the mid-pipe...

So, what do you all think? Lextek or BW? Merge differences aside, both look pretty good to me. Only nitpick is the BW doesn't have a center stand bump stop.

Looks like Lextek doesn't ship to the usa. Too bad. Guess I'll wait for BW's header, but that Lextek one does look nice though.

Well, we have to start somewhere! At the very least, we need at least 10 people who are in or we're getting nothing. If we get 20 or more, then that will open up more possibilities. I want a header, so I'm in!

Well, if Gabe is back on board, then that's likely our best bet. You've already contributed a lot to header development, and picking up from where we left off seems like the best idea. Perhaps we should compile an updated list of everyone who's in? However, I believe one of the obstacles was that we were contributing to buying a header whose performance was unknown. Having just one proof of concept with some comparison dynos would speed up progress a lot. My guess is things would go 100% smoother after we have some photos and data.

Thanks for sharing the good news, keef! I am definitely interested in a full system, but I need to know cost of system and shipping from AU to USA. It ain't gonna be cheap for us over here. I would be more interested in the stainless exhaust than Titanium since Titanium will probably cost at least $2k if not more due to the more complex bends on a V4 vs. inline engines. Do we have any updates on Tyga/G-Force and Black Widow?
