Split personality, I fake being smart
The one's you ordered will probably be best as they don't list a smaller inlet
175 likes the longest cones you can get on there, don't think the 200 will be any different.
They WILL act as amplifiers around 10~11,000rpm if things are working properly
If they are not welded you can probably compress them down to 1-3/8" or maybe a little smaller?

Can't is a four letter dirty word
i didn't mention before that the catalog has them as 1 1/2" OD. We now have the short and long with different tapers. We also have a stock set from another cb200. We want to learn how the different pipes and tapers impact performance. Our plans are to test the duals and then build a two into one. We want to see if we can see the negative pulse on the dyno.crazypj said:

...is that a step in the primary or just a weld?

Did Honda manufacture the step in the stock header for performance? Both the cb and cl header pipes have a step at about 19" and are constructed using a pipe within a pipe. The id of this first 19" is 29mm and after the step it goes to a single thin wall that is 31.5mm.

yours is more "actual" from what our Dyno data says for how this honda is making its power. But this is with a stock cam and we haven't let the little gal loose to breath freely...yet. 11.5 to 17.3whp isn't bad for this anemic cam. The velocity stacks alone made a .7 hp difference. Very curious to see what tuning the exhaust will do. Finally getting a grasp on what the wave tuning is and how scavenging works. Took a long time to wrap my head around it. The sound between the open pipe and the reverse cone was enlightening and then removing the baffle and opening up the reverse cone even more shed even more light for a visual picture for what the pressure waves are doing. I know Kop will laugh his arse off when he reads this. The problem I had with teachers in school is they wanted to tell me and not show me. But if you show me I get it. Zeke is the same way.Sonreir said:

Honda just made the pipe dual wall up the point at which temperature had dropped enough to no longer blue the pipe. No wave tuning going on there I don't think.
And nothing like the sound of a bike coming on the cam and the pipe as revs rise. Our 175 sounds like those old TT sound Stories of the works Hondas back in the day. We don't rev that high, but it sounds similar. There's quite a change in exhaust note as it gets up there.

my turn to be a Teazer... Three places to find out where it came from. How to build a functional cafe racer by Sonreir, a AG Bell's four stroke tuning (which took me kicking against the goad for 5 months before I picked up a copy), and David Vizards Porting book.1sttimer said:
