How much?
How much its worth, and how much hp gives you? Its emision friendly right? im guessing you get to keep the catalitic converter and stock oxigen sensor on its place... right? |
I've seen one on ebay that has 4-2-1 configuration, what are you toughts about that design compared to the 4-1 design ??
does it makes a real difference? |
for better fitment we recommend the Vibrant header combo now. much better performance and much better fit than the OBX;
