Im wondering if anyone has ever gutted a header on 2008 model and had good results.It seems to me that it would breath better and run cooler. If you did something like this would you need to remap?

^^^I noticed Hub answered you back on this topic in Performance Upgrades.

Stock pipes should give best all around performance. I am tired of their looks and sound and weight, though. I plan to go with a full system Alien Head and then I will have no cats. I'll be hanging onto the stocks and keeping them fully intact.

Thanks again Hub.
