Hey guys, i have an 03 WRX with an after-market DP, and muffler. I will be replacing the muffler with an SRS exhuast system, and my buddy told me that there is a slight leak coming from the downpipe, i also felt it after he showed it to me. He recommends replacing it when i put the new exhaust on but, my father says to ride it out until it becomes to real problem. Obviously i agree with my buddy because i want the best for my baby, but i would like to know what could happen if i left it on there and, didn't change it(good or bad)! i was going to get a 3" DP from godspeed just because it's cheap, but would like to keep my setup right now. Please help!
