Works perfect does have dent to clear second engines air filter so it would not burn n melt them but does not affect how it works.  Was I fully built 1995 seadoo speedster with twin 720s , R&D says they won't work but they will with the slight modifications if that's your use for them then email and I explain what it takes 

Those boats are fast and nimble but with theese pipes they are a rocket small light boat with lots of power

Pipe has been somewhat polished 

I have used these pipes on seadoo Hx , XP's and Seadoo Speedster,  these are great pipes you cannot beat them add more take off power more RPMs and more horsepower and torque in my opinion the best pipe out there for a seadoo had tryied others that do work well also but over all power I like theese pipes not just top end
