Thanks @RLJ10X you answered that perfectly for me. Im towing an enclosed trailer to PA and was looking to give the 5.7 some performance increase if I dont trade her for a Cummins first.JR, Shortys bolt up just like those awful cast iron manifolds. Other than gaskets, you don't have to change anything. I replaced my manifolds BEFORE any of the bolts broke. An ounce of prevention is worth a pound of cure.
I've read where you pick up a little HP with Shortys; around 20 HP with a CAI, and a tune. But I can't verify that. I could never detect and difference. The big reason I went to Shortys is to never have the hassle of broken bolts.
Everybody can do what they want. But to my ears almost all loud exhausts sound like a four letter S word. I don't want the attention, and I don't need to mark my territory.
Oh boy! It was my lucky day! I discovered the most Aft passenger side header bolt was walking out and was not broken. I could just barely believe it. All others in tact and look great. Got about a qtr turn on each collector bolt. Crazy! She quiet now! I was ready to kick her *** outta here. We good now!I gotta see where my BBK shorties are leaking. Installed 2 yes ago. BBK says use ARP hardened bolts. Spoke to them today.
