i was convinced that it wasn't an exhaust leak because i reinstalled the headers and the niose was still there, but now i think it may be a bad gasket on the drivers side. i just got my car dynoed and i pulled 260.5 and 299.6 with my boltons and i was curious what kind of gains i would get if i took apart the car and changed that gasket now? also is it bad for the engine to have a leak like that? thanks for the help...
