Use as much seafoam as you want, the whole can if need be.
After seafoaming, there are no leaks in the system. This is simply how the car sounds with a divorced 3" downpipe, and stock exhaust on everything else. I'm thinking about putting this DP up for trade for a bellmouth catted DP to see if that will solve the problem.
This Perrin is a real nice pipe, It just doesn't sound right on my car.
