im sure they are but wana make sure.. the 5.3 and 6.0 should be the same as a 6.2 on bolting up for a header correct? all the ls family is the same right? reason i ask is thinking bout droping 250 on a set of pacesetters and building a custom y for tops 200 instead of spending 1500 or more... and 1 3/4 will be fine since that and intake will probly as far as i go from where i am now... thanks

 

Yeah they will bolt up no prob its just most of the more expensive kits that are 6.2 specific i think use 1 7/8 pipe and of coarse the bigger y pipe. but if your making your own then dont worry about it.

 

sweet thats what i thought thanks man!
