OH, the whole point of a aftermarket header is for ebtter flow and weight loss no?

True statements, I am not concerned about performance as much as if it will damage the engine. These things are known to pop in time even with a good straight header. I am content to run it since its been run that way now along with the tweaked radiator. Very expensive exhaust that you can't buy jack for except a decal or a spring

I priced a full M4 GP stainless black can system for $910. I may go that route anyway and sell the Akro cheaply online. The Akro even has a carbon can
