That's not even close to what I'm saying! You could never "COPY" the dimensions of the IP2 and mod you stock pipe and expect it to perform the same. You need to engineer the stock pipe to perform how you want it to perform. You can't just cut and slap on some tin can and weld it just to make the chamber bigger "hack" it together and expect it out perform the IP2. Well you could but you probably have a name like "hack"munch. You need to decide how you want the bike to perform, consider your mods, and run a gauntlent of forumlae to calculate the correct dimensions of moddification for your pipe. This has been done numerous times by people who understand the construction of a 2-stroke pipe. If you read the posts about modding the stock pipe it will clearly state that of the calculations performed and the trial and error tests, the dimensions that have made the most improvement are the ones that have been posted time and time again. The construction of a 2-stroke pipe is a science, it cannot be "hacked" together as "hackmucnh" has stated. However since we have done the dirty work for you and provided the best dimensions for an "all-around" performing pipe, all that is left to do is cut and weld your pipe according to those dimensions. That pipe will not provide more rpms than and IP2 b/c it's not designed to. It will provide more power than IP2 or stock and more rpms than a standard jetpro. Giving you a great all around pipe for the cost of the wire in your welder. It however, as stated time and time agian will not be made of high quality material as the aftermarket pipes. It won't last as long as an aftermarket pipe. It will need to be reinforced with an additonal mounting bracket for the silencer to prevent the pipe from cracking. Also the stock pipe off a L7 cag is far supeior to that off the other FF & HF cags and that is the only stock pipe I recomend moddifying!
You guys that want to mod your pipe, go ahead and try it, don't be discouraged by people that can't weld or have had bad success due to lack of knowledge on 2-stroke design like this guy. It will perform all-around. It won't be high quality. It won't beat the IP2 in rpms. It will save you money. You will have fun experimenting. And you will have bragging rights when you're done. For those of you who don't want to then I highly reccomend the after market pipes, I have a jetpro and an IP2 myself and am very happy with them both. They perform great for there intended applicaton. However, I race 2 different modded stock pipes depending on track conditions!
If you wish to mod your pipe to outperform an IP2 it is possible and the dimesions of the pipe will in absolutely no way at all resemble the IP2 pipe, the stock pipe or the modded stock pipe. This pipe has been designed on a profesional 2-stroke pipe engineering program, by proffesional automotive/mechanical P.E. engineers working for a proffesional 2-stoke manufacturing company that I am not at liberty to disclose. It has been engineered for optimal wave refraction utilizing the header tube and divergent cone from the stock pipe. This is a highly modded stock pipe and it will
KILL an IP2 pipe in power and topend! Below is a pic of this pipe sitting next to a stock pipe.
Hackmunch don't be jealous b/c you don't have this
... LOL!
