Default odd noise....

Ok... I have long tubes and ORY... and when I had stock muffler on there *with a cut out* never heard this... I then added a SLP LM.... and now, like when you let out the clutch and you dont over rev the hell out of it... or when the motor is cold and you let off the gas at about 2.5k... you hear this ehhhhhhh crazy *** noise... sounds like something is hittin under the car REALLLLLLY fast.... is the pipe where it runs over the axle hittin? sounds like its right under either the passenger seeat or the passenger rear seat... any ideas how to test and fix?

well, first get under there and look around see something rubbing? no, then have someone start it up, look under there, most likely something is rubbing.

After a few weeks of driving, there should be an obvious rub-mark. Might want to check your tranny mount also. I though my posi unit was going out in my old 10-bolt, turned out to be the trans mount.

99% of people's exhaust hits under the driverside floorboard.

Thats the tunnel brace, you can take it off and throw it away if it is a problem. Almost everyone with true duals throws theirs away.
