sweet anyways when i get my car i just plan on gettin an off road h-pipe and put catilytic converters on it

[germanrocker]

that defeats the purpose of buying an off road h and if you do that it will probably end up costing you more.... if you are going to put cats on them just buy a h with cats on it
