Do it! You won't regret it, the sound alone is worth it. I had a 2015 EB Mustang for about 9 months.. Great on gas and fairly nimble, but I've owned 3 other pushrod 5.0s as well as an LT1 so it had to go.
Just installed my Progressive springs.. Should've did shocks and struts at the same time. Ride is great and hopefully it gets better with pro action non adjustable shocks.
Well I got home from work and got a chance to inspect the manifold. And it's cracked.. I emailed Autonation WBL hopefully I can get it exchanged quickly.
