It's all about the aesthetics. The kink is an eyesore. If you were gonna design a custom header I think the first thing you should do is eliminate that kink.

Well, it does depend on what muffler you use, which may or may not need additional clearance back near the rear axle. That is the point of the kink being made separate from the header, so it can be used or not, depending on your individual needs.
Of course the header can be made with the kink built into its primary shape, with the least noticeable being at the headers 2nd bend where it turns back toward the rear. It's all one piece that way and the extra bend would not be an eyesore.

Optional for who? Optional for someone who actually wants to put a good aftermarket pipe on there or optional for the idiot that wants to keep his factory pea-shooter with a huge header?

Put it this way - if you make it so the header points straight back, I'll buy one. Make it a factory replacement requiring a kink, count me out.

I agree about the kink; it looks like a kink...
I also think that anyone buying an upgraded, aftermarket header is bound to be using an aftermarket muffler. There would be no point in upgrading the header only to install a big fat factory cannon muffler on the other end.

Having said that though, it would also be hard to decide how to change the angle of the exhaust so that it would work with the widest variety of muffler options. Some of those would surely need some sort of adapter anyway, no matter how straight Lancer makes his header.
Right?

Of course, if the header is a normal single wall pipe, I imagine you could probably bend it very gradually, or have it bent slightly as Lancer is suggesting to accommodate whatever muff you're using and get a straight looking pipe from it...

I know I'll be looking at those down the line, Lancer. Let me know when you get them ready!! Wink

Any other pipe requires it to be kinked and looks horrendous. This is the RYCA setup: If that's what you prefer, you simply have no taste.

See, you keep talking about "adding" or "building in" this bend but you just need to change the second bend, not add a third bend. Adding a bend is just gonna make it look like the BCB pipe which also looks terrible. They all look terrible. The problem lies in the second bend in the header, don't add another problem.

No kinks, no added bends, just a different second bend so the pipe can go straight out the back. This is the Raask exhaust for our bike.

I will post when I get it and have had a chance to play with it a bit, mark and measure to send back adjustments to be made, then a final prototype to insure all is good. If all goes well I expect it to take at least 4-6 wks for the process.

Don't know but it would surely drive the price up to the range of the Raask pipe.

This one looks like the bike was laid down and something hit the pipe.
