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?

im not sure if you are a member on this site but it helped me out a lot when i had my nova. its stevesnovasite.com. a lot of really nice cars

Question is there too ;)

Want a 3 inch X pipe? ;)

How much? Trade you some supps? :mrgreen:

If you can pick it up, its yours. Just taking up space in my garage at this point.

PM me with details. I can leave you a can of Jack3d with 2 scoops missing for your troubles :mrgreen:

nicee. figured id try haha

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 !!!

I've got the tire crayon in my car ash tray! Heh. Thanks man.
