exhaust pipes ..

[voivod]

Am looking for a short thin exhaust for my rd. is there a thing? Can people put up pics of pipes so I can see the difference?
What effect would that have on performance? Is there a program I can use to try and see?
thanks steve

nobody with pipe software at all?...

[lcowner]

what u mean short thin?dont think ul get anyone giving u drawings ect for pipes ,it wud be like me giving u my credit card and saying work away..............

Was trying to see what the effects would have with different shapes /lengths ....was nt wanting to steal it. Trying to fit 4 pipes under a 4cyl LC....trying to see when I can rob an inch or too

I also have ordered a set of black chrome from gibbons today.
Just have to save hard for the next ten weeks.

You cannot just say short & thin, long & fat.

2T pipes is a Black Art and there is more to it than that. I understand pipes and know what should happen by changing different parts of the pipe, have also designed my own BUT nothing as good as Kenny's TSA or Martin77 pipes.

There is freebie software, most out there is done in Exel and are very basic. Not rely that good
and then there is stuff you got to pay for like engmod2 BUT then again it takes years of research to even begin to know how to use this software as human effort is needed knowing more than a bunch of figures that are typed in ( Black Art )

There are very good write up's by people like Jenning's and a few others. Google that and you will find there books. I've read most of them out there over the years BUT understanding and knowing how too are very different things.

Then after all that you got to build the pipes, cone rolling is a fine Art again and there is software out there to layout your cones, I have cone rolled and am rubbish. Hydroforming is another way, little bit of Maths to work it out BUT still some good fabrication needed ( that's how I build mine )

I love pipe theory and seeing people's builds, I can fabricate, weld and know the theory.....Can I build pipes worthy for others or design a great out and out pipe....Nope.

But google and read 2T Pipe & Tuning theory's. That should keep you going a few years.

lol...Reason is I have looked for ages a peoples pipes ....some are shorter to the start of the fat bit...some longer.
Some have long fat bit...some short.
Some fat bits are HUGE...some are very slim.
Wondered what effect these have on pipes...how it works etc. Again I can solder/ weld to a point...NOT gona try and make a set for the bike..just trying to understand more on what it does ...and How I could maybe rob peter to pay paul on dimension issues

If you want to have a little play with dimension software and a good read of Jennings Book on expansion chambers drop me a pm with your email and I will get it over to you

I'd speak to kenny (TSA) as if anybody can work out what is best he can.

You should get something to work, if you look at the old microns/allspeeds they are quite slim and had a reasonable performance.

Will speak to kenny again about this . Just trying to research some stuff first. Always feel better to have a wee bit knowledge/understanding when asking for something to be done that way I can understand better when am told NO or YES
