It is resonance in your exhaust. My car does this as well. You can put on Corsa axle-back mufflers to get rid of it, but other than that you just have to deal with it. It is nothing bad, that's just the nature of the beast.

 

I have FRPP X pipe and JBA axle backs and there is no resonance, I had a customer with Flowmasters and an O/R pipe........wooooooah it was horrible at 2,500 rpm, would shake your teeth.

 

You may not notice it if you have the radio on, but if you turn the radio off and have the windows up and cruise in 5th gear around 1300-1500 rpms (mine only does it right at 1450) you will feel the resonance. It gets amplified by exhaust mods unless you do corsa mufflers.

 

oh ok than i didnt think about that i have the magnaflow mufflers welded on tho could it be from that then ?

 

yea cuz its a noise that comes on only when i hit like 1300 an than after that no more noise ok that makes sence tho im actually want to get rid of my magnaflows i hate them bc there so quiet im gona sell them for like 150
