Review on 🚚 JBA (1850S-4) 1-5/8" Stainless Steel Shorty Exhaust Header for 2014-2015 GM Truck/SUV 5.3/6.2L by Tone Hatton

I did CAI, oversized throttle body, throttle body gasket, ECM tuning, Borla Cat rear. I feel like adding these headers made the most noticeable difference. You can get to the driver's side without dismantling the steering shaft, only tricky. I would recommend buying new manifold gaskets for the Y-pipe rather than reusing the old ones. My only complaint was that the gasket from the manifold to the head didn't fit well in the manifold ports. The driver's side was leaking and had to be replaced. I contacted JBA and they sent new gaskets. I had to cut the gasket down the middle to move it and close the port better. See fig.
