WIERD SOUND out of the blue

[buttuz]

hopefully I can get some help first gear not a problem 2nd gear the sound is much deeper and growling allot deeper as well as 3rd and 4th. I have stingers and g5x2 cam for 6 months now and the sound that I just heard was not the same sound that I am used to almost feels a little slower to i don't have any clue what could cuase this deep sound its not so much that it sounds bad its just a different sound then before there are 13000 miles on the car could it be that the car changes its tone with more miles on it I am just hoping is't nothing serious. My friends car has stingers and my car is much loader then his even before i put the cam in . I am aware that every car sounds a little different also but this is very strange to me that it would happen out of the blue.

carbon build up on the stinger mufflers is reducing some of its muffling ability. normal i would think.

I would like to offer an opinion on what the problem is but I'm confused by your post. Are you concerned about engine noise, transmission noise or exhaust noise

You mention Stingers and a cam and different sounds in different gears. If you'd care to try again maybe someone can help.
