hey guys... i dont ask many questions here, but i have one
to ask right now......
Im hearing a loud hissing sound when im racing my car...
but the sound only appears when i go over bumps in the road...
i.e.: green light, going thru first pulling hard, slam second gear and still pulling hard, when i hit a bump or ripple in the road i hear the sound for a split second, like when the wheel is spinning in the air
before the tires lock back up with the road after going over the bump.....
i dont hear the sound every day during normal driving, only when going thru the gears hard!
I only have two ideas as to what this could be.....


1. I have a leak somewhere in my exhaust near the headers and
cat connection.
2. Its just the sound of the wheel spinning faster because its
in the air not connected to the road.


i welcome all ideas and suggestions
