A question regarding this.....well i dunno how to explain it but here i go.....i own an auto 2.4L TE, when i bought it, the previous owner had already installed a 2.25" cat-back exhaust on it with a straight-thru muffler on the end...("prospeed muffler" or sum Sh1t)

anyway....wen the engine is cold and has just been started up, it does this highly irritating rattttatatatatatatatatatatatat noise between 2500 - 3600 rpm.....it only does it the first time it reaches this rpm range....wen i go between this rpm range the second time, its perfectly fine....and the rest of the time, this rattttatatatatatatatatatatatat noise is only noticeable up at about 4800+ rpm

I didn't know wat the hell was goin on, so i took the car into Carline in Perth and they heard it and sed, that the magna has a Raspy engine....some explanation that was! but yeh i still haven't got a clear answer to y it does this. can someone help?
