Thanks to everybody that responded to my post, but now I have a problem, or at least I think I have one.
I just finished intalling my Borla Cat-Back and it fit wonderfully. Only problem is, when I give the car gas, I can hear a sputtering noise. I noticed a little grease in the pipe before installing it, is that just the grease in there and will it stop, or is there something wrong that I need to have checked out? This is the first day that I have driven it, actually I finished the install about 3 hours ago, so hopefully this is just a temporary thing. Thanks for advice.
