Has anybody had an issue with the stock exhaust leaking? (car is an '03) Right now I can hear an exhaust leak somewhere around the stock manifolds and midpipe. I checked all of my plugs yesterday to make sure one of them doesn't blow out of the head! They were all fine. Have not had a chance to get the car in the air yet to check the exhaust, and was wondering if there was a specific "problem spot" with them. Which side manifold does not use a gasket? Could that be the problem?
