Which one is better? One piece or two piece ceramic header from DC sports?

 

neither is really better than the other(atleast performace wise), i've heard its slightly easier to install a 2 piece but i had absolutly no problems at all when i installed my 1 piece. just slipped it under that car and that was that. i guess a 2 piece would be more prone to run into problems with leaks or w/e but that shouldnt be a big concern.

 

I've read two pieces are heavier.

 

2 piece are heavier.. only difference i see,, only reason i could even think to buy a 2 piece would be for some type of custom setup..
