piping size ??

[wkx]

Dear master n guru's,

i'm newbie here.. just want to know which one of the piping size more ideal with this kind of setting :-

a) Header 4-2-1 custom made
b) RS*R magic muffler
c) H22A type S (SiR)

my next project is to match those with RS*R header or Skunk or mugen .. for time being i'm using 2.5" piping.. but feel not power enough.. may be any suggestion or opinion ?? thanks for the reply

2.5" is the best size for a mild H22. You will have to do quite a bit more to the engine to need any larger.

2.5 will be best it will have good flow and keep the back pressure thats needed to still make the power

Please explain to me how backpressure is needed. I'm very curious.

no doubt they already told you... 2.5 = best

no doubt they already told you... 2.5 = best

So why say it again?

And it's not "best"... just best for a mild application. If he goes with extreme modifications, larger would work well.

you're talkin about MAJOR mods now, its not the same

agreed on this, i wanna hear why. I can tell you from this point backpressure isnt even a true concept. its all about diameter and gas velocity. fluid dynamics really. also a basis of the venturi effect and such.

just keep that 2.5 on the h22. the most power will come from a smooth flowing mandrel bent exhaust. use straight through mufflers and resonators. essentially you want the least number of bends as well.

2.5 will do , also how is you torque step pipe designed ? i have a custom one made from magnaflow . the more air you bring in the motor , the more you want coming out.

so the best option is 2.5 with the straight piping ?? i heard it's good for pick up.. what about the long distances ? isn't that will kill you top speed ?? i'm still looking for one setting piping with my cb.. thanks again for any reply..
