All; I just pulled the car out for the upcoming summer of racing and in the off season installed MAC O\R Prochambers and Cat Back. After starting the car and letting it idle the other day, I noticed 2 1/2 sq ft puddles of water under the car from the exhaust outlet and junction between the tips and cat back. I also stuck my hand behind the exhaust and it was VERY humidified. What would cause this condition? I was thinking that without the CAT's the exhaust gas has enough time to lower it's temperature and condense by the time it reaches the tailpipes or that there may be a reaction occuring with the exhaust constituents and some sort of coating or something inside the pipes. I never noticed this condtion with my previous BBK O\R X pipe mated to stock "cat back." Any suggestions? It is not the tune because I returned the car to stock to verfy the tune and the same condition occured. Thanks in advance!
