what longtubes for 5.3

I've come to the conclusion that the Pacesetters are just too big for my setup. The pipe is too big and the exhaust velocity is down. Up top the 3" pipe makes more power, no doubt about it, but overall 2.5" is just more enjoyable. Gotta keep that exhaust velocity up. I managed to finally pick up what I wanted from the beginning - catted Dynas - so I'll be pulling the paces off and putting those on for good. A lot of trial and error with headers for me. For daily driving the 3" y on the pacesetters is just way too big for a 4.8 or 5.3, of course unless you are boosted or something of that nature.

none of these headers will fit a 5.3
they will only work if you have either a 4.8 or a 6.0
the 5.3 uses a different canooter valve modulator on the EGR tube crossover, making the pacesetters and dynatechs ineffective at the rpm range we want to stay at, to make a constant power level, its a simple lambda coefficient.

But on a serious note, let's not forget to add StainlessWorks to the list, I'm more than happy with mine

it all depend on where u live, and how much money you want to spend........ your not goin to see a significant difference in performance from one header brand to another........ on the other hand, you will see a difference in quality. so just keep that in mind when choosing.
