Default 1 3/4 or 1 7/8 250 shot
So, with my car being a hci ls1 with a 250 shot of spray, should I keep the 1 3/4 or make the move to 1 7/8.

Well I'm sure the bigger headers will help with that big of a shot, but weather or not you switch is up to you obviously. If it were me and it wasn't a dedicated nitrous car I'd just keep my current headers. That's just me though

Although mine was NA (LS1) I ran 1 3/4 and then 1 7/8 and dynod. Saw zero difference from 0-3500 but above that there were gains.

My buddy did the same thing on his HCI LS1. Saw no gain up to 3500 and gained exactly 5 hp at peak. Same dyno one week apart
