HOLY CRAP FINALLY the headers will arrive in about a week, so either the weekend of July 15-17 or the 22-24 is the install date. Im working with a cousin who knows what he’s doing, but I will try to help to gain experience of my own.
These are 1 7/8" Kooks Longtubes going on a 2013 Challenger 5.7.
Is it something like removing the motor or heads to put them in? One look under the car shows that it’s quite tight.
What’s the reason that it usually takes 6-8 hours?
