I was wondering if there was a big advantage to aftermarket shorty headers? I see BBK sells some chrome ones for around 300 a little more for ceramic coated. Will it add much power over stock? Does it have a big weight savings over stock. Dont want to do long tube headers cause of California smog. Most shop cant really tell the difference over stock and aftermarket shortie. So I was wondering if anyone knew if anyone knew if it offers a good gain? And does it change the tone alot.
