I'm looking to do mine in the next couple weeks as the correct fix from the clamps that I've had on for a while now.

my question is for those that have replaced them, what brand did you wind up going with?

Why are you replacing the manifolds? They're pretty stout, and I don't think they're prone to cracking. Did yours warp with the broken bolt?

I think I'd opt for shortys if that was the case. But that's just me.

Would definitely go with shorties if forced to replace factory manifolds. Won't provide a huge net gain, but better than nothing.

I have 3 clamps on them now due to bolts that have broken off over the years. (2 driver side and 1 passenger) Since I'm pulling them off to do the proper fix and remove the broken bolts, I figure I have no idea of their actual condition until they're off and I'm doing new gaskets and all...for the $120 I'll just go new and have peace of mind all will be sealed up nicely. I have no experience with shorties or anything aftermarket like Borla or others so just go for simple OEM fit and call it a day.

After a couple of years, I still have clamps on the rear broken off studs, both sides. Everything is still sealed and quiet. I plan to leave it that way indefinitely since no other stud heads have broken. I'd probably just clamp those, too (sorry if that makes you cringe)... cheap and fairly easy.
