go with the full yosh system header to can.

 

Your right about the bang for the buck. Did you use the same Z with the same tires for each dyno? The tires can (most likely will) vary the results of a dyno. In the DW shootout, the jets were off on the Yoshi. Im not a yoshi fan by no means, at all, but I know their 440 kit is one gnarly kit.... Id still go with CT though.

 

all of the zs that we have dynoed had the stock tires on thm they were all customers bikes so It was a fair comparason on machine for machine We are very close to sea level and also have air/fuel meters to jet the bikes correctly. Mine has been the only one that has been dynoed with any other tire but the first dyno on mine was with the stock tires but I race mx So now its running holeshot mxs and they are 18s.

 

My CT pipe is not that loud, louder than stock but not nearly as loud as pro circuit, and yoshi.
I noticed a gain in power, it will easily rev up to the rev limiter now.

By dirt wheels test the yoshi was not jetted properly, so they did not rank good.

All pipes give 2 or 3 hp gain, not much. But when you only have about 30 hp to start with that is a 10% power increase. I was having second thoughts about geting a pipe also, untill I was told that.

 

I heard Yoshi pipes put out a weird looking power curve on the dyno sheet too. I personally wouldnt ever buy a Yoshi exhaust unless I got a great deal on one.

 

can u get a full ct pipe and yoshi 450 kit, or will it run bad without the yoshi exhuast?
