H-Pipe dimensions

[gashog]

I have a buddy with a bender and I was thinking about making my own. Does anyone happen to know the dimensions of an aftermarket H pipe?

just pull your stock pipe off and use that as a template.

So how are the aftermarket pieces different? Larger diameter? Straighter pipes?

Does anyone have a comparo pick?
