You are not going to be able to bolt any long tubes to your factory y pipe and shorties are a waste of money. There are many threads about this try the search button out

Headers that fit a 4.8 will also fit a 5.3 or a 6.0 engine. You buy the headers to fit the chassis. Long tube headers give you the best power gains. Most of the headers are so similar, there is very little difference in performance. Stainless steel headers are nice because they don't rust as much. Check out Maryland Speed or Texas Speed for available options or roll the dice and gamble with cheap eBay headers.

I have been running pacesetters for about five years, never had a leak yet, great power gains. I do run an offroad y pipe however, which will bolt up to stock exhaust. You can always weld in some cats to a modified offroad y pipe.

So if I go long tube headers I'd need to redo my collectors and mod my catalytic placement and such? Also why do shorts do nothing? They all claim to have increases in hp fuel econ and torque. Also if I went shorties then put in a new y pipe set up that is larger dia then stock w more free flowing cats (or just get a magnaflow y pipe w hi flow cats) would that make shorties worthwhile?
