Porting exhaust manifolds
I am ready to purchase a set of headers for my BB Camaro, but I'm looking into Extrude Honing the exhaust manifolds. Doing so would reduce the problems associated with headers. Anybody had this done? Did you see a noticeable improvement. I know there are those that will say it's a waste of money for minimal benefit. But the Fast(Factory Appearing Stock Tire)Racers are making huge horsepower and running 10 second times in 1/4 mile through the exhaust manifolds. Thanks
