I don't work for poston or anything like that, but those headers are worth it imo. Their the only one who makes them for us now, their ceramic coated, they easily clear all stock componets and are direct bolt on, they work with the stock up pipe, they are clearly a better flowing header just with side by side comparison. I would call ahead and request the welds be inspected before shipment, get a name too. I would recomend their 2 piece crossover also, and use a band clamp, don't weld it,... to help prevent cracks in the future. I'm sure you may get other opinions, but what has worked well for me I'm hoping will work well for someone else.
but yaa, that is alot of money though
