KZ750 4-1 exhaust size?? was created by mike0537

I am planning on building my own exhaust for my 750. I just want to know what the 4-1 collector output size is? I'm thinking it is around 2". I only have the stock exhaust and would like to know what Kerker, VH, or anyone else used as exhaust size so I can keep it the same for back pressure reasons.

Thanks!

Multiply circumference by .3183

I always found it easier to multiply than divide, but then again I come from an era of slide rules!

To the OP I can answer your question tomorrow. I have the Kerker but it is about a half hour away!

You guys are KILLING me! If you had a tape measure, why wouldn't you just measure the ID/OD of the collector! :laugh: :woohoo: :laugh: :silly:

the problem is where the pipes collide it is very small and hard to find a y-pipe to fit.

Depends entirely on kind of pie,I generally have found in the case of peach/cherry or pumpkin pie that the 1 pie to 1 fork generally fits into my plans rather well! :woohoo:

I can put my handle bar in the exhaust pipe and jiggle it around a bit where I cut it off so yes a 7/8" handlebar plus jiggle x (pie x 0) equals about 1 inch x 2 = about 2 inches then the baffles for restrictionary purposes = pumpkin pecan

Chicken pot pie would involve an entirely different calculus, sort of like pie in the sky, and sometimes pizza pie (if triangular slices and NOT rectangles).
