Dual Exhaust
kaptn,
I don't think it will fit if you mean an underbody system. We have 4 inch duals in stainelss and aluminized that we have been selling for almost a year now and it's pretty tight fit as is, in fact you must have a 4 x4 to get them to fit already. Hope this helps you out, call me if you have any tech questions.
