Headers
#2
Headers are expensive for the LS4 and probably will be a pain in the *** to put on too.
If you plan on ever upgrading to a Turbo you won't need headers you can just use a variable cutout to dump the exhaust right at the downpipe... which will provide all the same benefit of headers anyway assuming that you are getting headers because somehow they are an improvement over the stock ones with regards to flow.
Headers look better... but that gets old after you've shown the car to your friends a few times... I'd keep the $1000.
But if you want to waste some money IMO go ahead and buy some...
