i am thinking of installing 2" down pipes with either a 53000 series catalytic conversters or a 94000 series. The difference is that the 53K is applicable for engines up to a 4.2L, and the 94K is up to 5.9L... Right now the engine is stock, but i do plan on modifying the engine... I want the car to be the quietest possible... Has anybody had any good or bad experience with these catalytic converters ???? thanks in advance guys.....
