I installed a set of Dynoport pipes on my 98 FIII and it really woke up the engine. I'm guessing the Mach Z pipes would do the same thing. The Dynoports are end dumps,Didnt the Mach have center dumps in 98? I kept my stock carbs and jetting with no problem so far (2nd season) Chuck.nate b said:Would I gain anything on my 98 formula 3 700 by installing pipes and dynoport cans off a 98 mach z? how about the carbs?
