okay, i got the SLP catback a while ago and LOVED the sound difference it made. i just installed my UPR offroad x-pipe the other day and i've noticed an awful and disgusting ricey drone/fart-can noise between 2250-3000 rpms. it sounds great everywhere else in the powerband, but the sound is driving me nuts!!! i plan on getting cats welded in it on wednesday, how much of a difference will that make? i'm thinking it may be vibrating against something, but i haven't had a chance to put it back up to look. any input/help/advice would be greatly appreciated. is it just the particular x-pipe/catback combo? if i can't get rid of this ricey drone, i may have to take the x-pipe out.
thanks, steve
