212 predator exhaust

[HarryHighLife]

Just got myself a buggy with 212 predator, have a mikuni carburetor to go on it and plan to build myself a straight pipe for it from old pitbike exhaust.

Before making a start my question is: should I be following any guidelines when making my own header pipe/exhaust? Example, does size of pipe make performance differ? Optimum size and length?

Thanks

Is the exhaust from a 2 or 4 stroke bike???

I’d probably go with 1” OD x 0.065” wall thickness. About 12” long.

The exhaust is from a 4 stroke braaap 150cc pitbike. Thanks for the awesome info. Was exactly wat I needed to know.

Thanks all.

Don’t know how much it cost to make one, but amazon has some for $24 and up that are straight pipe.

I picked the buggy up second hand for a few hundred. It's in good shape, engines still strong (needed oil change typically). Plan on keepin it as low budget as i can while still having a fun toy.
So I have two pitbikes (currently in pieces, will probably stay that way lol) which I took a 22mm mikuni carb off and a race pipe off another. Plan on altering pipe to fit, will be good learning curve on mig welder. Also took 2 rear wheels tyres off a small 4wheeler and put on rear of buggy. Definitely improved feel and look.

Sidenote: I have a 4 stroke, 150cc, 4 speed sitting round. Any good ideas for it other than a bike?

I always say bigger is better. Here is the exhaust on my gx120.

Is that photo shopped? Hopefully you keep it well covered. I'd be concerned about water, dirt, rocks or even a bird making a next in that big o' hole.

The exhaust pipe is off an excavator. I just had it sitting there to see how it looked.
