I already have the Polini pipe and I'm not planning on cutting and welding a pipe to fit with the pedals. (nice work on yours by the way) I'm just helping out my bro and he's a career college student with no money so we're going to do this with $10 worth of jets and some elbow grease. The polini pipe has to be better than stock. I think I am going to buy a few jets. Thanks for the input!
