I'm sure it's been covered 1000x but is there any manifold that's way better than the rest? I have a 4 mill stock cyl with 34mm pjs. It's on gas and has 85 hp on the dyno. The rubber upp manifolds on it are cracked so I need new. Should I just replace the upp or get another? Thanks.

upp will last about 3-5 years and then need replaced.  but any billet style with rubber boot is about the same way.

 

my personal fav is the trinity intake 2 piece, UPP, chariot. and there used to be a set with a center divider in it that worked well.  a lot of them just have the wrong angle and/or the wrong placement of the boot to work worth a shit,  OR they are the leakmaster internal boost bottle bla bla bla bull shit ones.

I bought the upp intakes locogato suggested from redline. The problem is mine had the crossover tube but the new ones don't. Is it necessary to run the tube? If so I guess I gotta return mine for some with the crossover tube version.
