Anybody fab up their own H-pipe?
I'm going to be installing the "final" exhaust system on the Nova soon, and while I like the 3" Summit system it does not have any type of exhaust crossover. I've got extra exhaust tubing, and have a plasma cutter and welder sitting there, so I'm thinking about trying to make one up.
Couple of questions:
1.) Has anyone done it?
2.) Does the crossover pipe need to be the same size as the rest of the pipes?

usually you want to keep the same diameter, if 3" you can step the crosover to 2.5".
the reason is for balancing left & right sides, so in all reality any suffecient size will do its job, (obviously 1" piping would not be a good choice)
also alot suggest if going to run a cutout,use a tire crayon and strike a line from header flange along pipes to muffle, let vehicle warm up, take a decent pass. where the crayon stopped melting/burning off is your most torque/hp point. install cutout at that area.
p.s. thats a old timer trick !!!
