any body have full pipe if so please tell me negatives and positives....and what jets you used also if you used rev kit ???? on a stock unit please ....thanks bigboy400ex

 

do you have one

 

no i want to know if anyone has one on there 400ex ????

 

thats probally the pipe I will get
like I said in an earlier post gt thunder rated
the white bros pipe top. And dirtwheels said the yoshi pipe could pull harder than the white bros. On that same note . The yoshi pipe for the 650 in the mx mag didnt kick butt it was average. to me the dyno run was almost identical to all the other pipes

 

Big gun's and LRD's are the best bang for the buck...I perfer the LRD...I think it is a better pipe because I have seen many problems with the big gun melting plastic....I have maier plastic (plastic that is suppose to melt eaisest) and hte LRD hasnt even touched it...$300 ya cant beat the power verse price

 

i did the full yoshi exhaust,didn't do a whole lot,it is almost 3/8" wider.i was told that i would't notice any power gain until i did motor work.the bike went in today,getting a 426 kit w/cam,ported heads,and carb.i did get up to a 170 main jet with exhaust and k&n filter with no lid.let you know how the new kit does.

 

now I heard that the yoshi pipe would be best for a 400 because it didnt have enough flow for a bigbore.

 

i know alot people bought these ..no one got any info are were to set jetting ...I work for a dealer so i will buy it cause it looks good and slipon made 3 horse ...so full should be id say 5to 7 .. i hope ...then will try xr250 ign box insted of white brothers.....

 

I noticed a huge improvement in power. The fit and finish is the best!

 

Why did you go with the TI setup?What carb do you have?What is your top end?Do you have problems keeping the front end down?
