I really like my Kooks with the green cats Y pipe... but they don't make it anymore...
Spark plug access is easier I think.. You'll NEED a 45* plug end spark plug wire (ceramic)
to avoid burning the plug side boot on the headers...
Headers (I believe) are almost always a benefit over manifolds.. But you'll need to weigh the
cost vs. benefit.. You won't see any benefit in power or mpg without a good tune by a reputable
shop/person.
On a stock 5.3L engine you would be fine with 1 3/4" primaries. The 1 7/8" would be overkill
in my opinion.
I have the 1 7/8 but I have 6.2L and I was supercharged when I put them on
