It is a Delphi. What brand do you recommend?

Another issue is this damn Pacesetter collector. It will not stop leaking. None of the muffler shops will touch it. I should eliminate them but it costs way too much. ZZP headers are over 1k so that’s not an option. I don’t have the stock Ported manifold setup anymore. eBay headers are garbage from what I’ve read.
Local muffler shops wont touch my headers. A local Performance/ fabrication shop BDK Performance could probably fabricate something but will probably cost a ton. PITA!!!!
