Smile Exhaust Length Query.

Hey all.

I went with straight pipe and a curve down. I've been reading a lot about exhaust lengths and am a bit lost. Should one go with the pipes of equal length (and does this mean shorten/lengthen a certain pipe) or keep them as they are? I'm degoated, ear shaved, rejected 42/142 and straight pipes.

Thank you for your info!

Kristoco.

42/142 might be a bit on the large side for jets. mainly the pilots. Ideally they should be equal length that way both cylinders make the "same" horsepower.

there is an ideal length however it requires doing some pretty involved math to figure out exhaust pulse timing.

not to mention, equal length pipes would almost certainly mean they both exit on the right side, due to the V of the engine. otherwise (example, by no means accurate lengths) the rear would end near rear axle, while front would end not too far behind the front foot peg
