As the the topic says I need some links to the info stated:

Stock ITR piping sizes, and spoon n1 sizes

I think they are the same sizes, but just need to confirm that. Hopefully someone would have these links saved somewhere, I tried searching google for the past half hour with no luck. THanks

 

can someone go out and measuer their stock type-R tip for me?

 

I got the same question
