Hey guys,
I have a 2000 Pontiac Grand Prix, that needed a new cat. I decided to also replace the o2 sensors, as they were pretty cheap. I ordered the magnaflow downpipe with cat from rock auto. Got it all installed with the new o2 sensors, and Have an exhaust leak where the down pipe connects to the exhaust manifold. Is there a tip to getting a good seal? I'm going to try and pick up a new gasket, going to have to be from the dealer, as no parts stores seem to have it. Any tips are appreciated. I need to get this through emissions.
thanks
matt
