so im going to order a UPR O/R X-pipe. im going to put it on with the stock catback for a few months, and im wondering about a couple things. one of which is how is it going to sound? anyone have a soundclip or know where i can find one? and two, what kinda HP am i leaving out there by not getting a catback also. i plan on getting the magnapack or Borla in a few months. im thinkin a catback would get me maybe 10 hp. thanks.
