i would ask somebody to borrow there stock h pipe, swap the two for the smog and once you pass put the off road h pipe(no cats) back on. the car sounds a lot better with the off road h pipe ![[Smile]](smile.gif) but if you want the car to stay smog legal then just buy a hi flow h pipe w/ cats which will have two hi flow cats which is smog legal.

Yuhknow, Im not sure about the headers, I think they're stock, they pinch together at the head?
look kinda scrawny.---thanks for the advice, where on the pipes is a good place to put two high flow cats? back before the muffler or up by the headers? whats a good heat shield material?--thanks again
