Will I hurt anything

[hondaguy2]

I am having my 300ex rebuilt with a new pistion it is getting bored out and i am putting in a wiseco pistion. My question is if i get a e-series exhaust will it hurt it during break in? Or should i just run the stock exhaust until it gets broke in? I don't want to ruin anything, any help is appreciated
:cool:

I would think it would be ok. As long as it is properly jetted.

I am not sure if it would hurt it or not?? But I think it would be better to do so! At least the jetting could be correct and would not have to take it back!

it won't hurt anything, just make sure your jetted properly;)

No it wont hurt anything, it will actually be better for it. Make sure you are jetted a size or two fat, this is good for breaking in a motor.
