Headers question
I have heard both sides to this. I'm looking to do a few simple bolt on mods (pulley, intake, tune) and I hear some tuners saying you need headers because the extra boost will melt the cats, and then I also hear some say you don't need headers. What's the consensus on bolt on mods without headers?

I'm saying that when you do other bolt on mods that increase boost (let's say 18% lower) do you need to do the headers at the same time because I've been hearing people say the increase boost/temps can and will create problem by leaving the factory catalytic converters on there.

yes, its possible to loose a little boost after a long tube setup but that doesn't mean that you are losing power. the car will make the power, but with less boost. less boost means less heat generated from the blower....

In simple terms an engine is an air pump. It uses air to move the pistons so more air in and more air out means more power. By reducing the restriction to flow coming out of the engine means less boost but possibly more power. As you go down this modification path you will find the next area of restriction whether it be intake (CAI, pulley, SC), internals (cam, lifters, etc) or outflow (headers/ x-pipe).
